Sri Sathya Sai Baba - When to say the Gayatri


Om Bhur Bhuvaḥ Swaḥ
Tat-savitur Vareñyaṃ
Bhargo Devasya Dheemahi
Dhiyo Yonaḥ Prachodayāt
Do not sing cheap and defiling film songs. Instead, recite the Gayatri. When you bathe, the body is being cleansed; let your mind and intellect also be cleansed. Make it a point to repeat it when you bathe as well as before every meal, when you wake from sleep, and when you go to bed. And also repeat shanthi (peace) thrice at the end, for that repetition will give peace to three entities in you --body, mind, and soul.
[‘Sathya Sai Speaks’, vol 13.34: June, 20, 1977]
Time, like man, has three qualities: satva, rajas, and tamas (qualities of purity or serenity, passion, and inaction). The day is divided into three parts:
·    4am to 8am and 4pm to 8pm have the sātvic quality
·    8am to 4pm are rājasic
·    8pm and 4am are tāmasic
The eight hours from 8pm to 4am are used mainly for sleep. The eight hours of the day (from 8am to 4pm) are employed by all
beings, including animals and birds, in the discharge of their day to day duties and are regarded as rājasic. When the four sātvic hours of the morning are used for engaging oneself in good actions like worship, virtuous deeds, and keeping good company, one is sure to raise oneself from the human to the Divine level. It is during the sātvic period (4am to 8am and 4pm to 8pm) that the Gayatri mantra should be recited.

Sri Sathya Sai Baba - Benefits of chanting Gayatri Mantra


Om Bhur Bhuvaḥ Swaḥ
Tat-savitur Vareñyaṃ
Bhargo Devasya Dheemahi
Dhiyo Yonaḥ Prachodayāt
Through meditation on the Gayatri, one can become aware of the inner motivating principle of the five elements, the five vital airs in the human body and the five sheaths which encase the Atma. Just as there are three basic energies that govern man---the physical, the metaphysical and the psychical, the ādhi-bhoutik, the ādhi-daivik and the ādhi-atmic, Gayatri has three facets, Gayatri, Savitri and Saraswati. Gayatri fosters the metaphysical, Savitri, the physical, and Saraswati, the psychical. These three karañas or instruments have to be cleansed and sublimated so that man can realise the goal of life. Through the recital of Gayatri mantra and meditation thereon, this great task can be achieved.
[‘Sathya Sai Speaks’, vol 15.11: June, 26, 1981]
It will protect you from harm wherever you are - traveling, working, or at home. Westerners have investigated the vibrations produced by this mantra and have found that when it is recited with the correct accent as laid down in the Vedas, the atmosphere around becomes visibly illumined. So Brahma-prakāsha, the Divine Effulgence, will descend on you and illumine your intellect and light your path when this mantra is chanted. Also repeat shanti thrice at the end, for that repetition will give shanti or peace to three entities in you --body, mind, and soul.
[‘Sathya Sai Speaks’, vol 13.34: June, 20, 1977]
It is essential to recite the Gayatri mantra at least three times during morning, noon, and evening. This will serve to reduce the effects of the wrong acts one does every day. It is like buying goods for cash, instead of getting them on credit. There is no accumulation of karmic (result of action) debt, since each day's karma (action) is atoned for that day itself by reciting the
Gayatri mantra.
[‘Sathya Sai Speaks’, vol 16.6:  March, 17, 1983]
"Sarva roga nivaarini Gayatri" (Gayatri is the reliever of all diseases). "Sarva dhukha parivaarini Gayatri" (Gayatri wards off all misery). "Sarva vaancha phalashri Gayatri" (Gayatri is the fulfiller of all desires). Gayatri is the bestower of all that is beneficial. If the mantra is chanted, various kinds of powers will emerge in one.
[‘Sathya Sai Speaks’, vol 28.22: August, 23, 1995]

Sri Sathya Sai Baba - Deeper meaning of the Gayatri Mantra


Om Bhur Bhuvaḥ Swaḥ
Tat-savitur Vareñyaṃ
Bhargo Devasya Dheemahi
Dhiyo Yonaḥ Prachodayāt

Gayatri, Savitri and Saraswati are latent in everybody. Bhur, Bhuvah and Swah in the Gayatri mantra refer to the body (materialization), the life-force (vibration) and the soul (radiation). Bhur means the earth, which is nothing but the combination of materials. This denotes the human body, which is also a combination of materials. Bhuvah refers to the life-force, which makes the body vibrate. Swah refers to Prajnāna-shakti, which sustains the life-force. This Prajnāna-shakti is known as constant integrated awareness. This is also termed as radiation. All three, namely, materialization, vibration and radiation are present in man. I tell you often, you are not one, but three—the one you think you are (physical body), the one others think you are (mental body) and the one you really are (Atma).
[‘Sathya Sai Speaks’, vol 33.04: Feb, 10, 2000]
Gayatri is described as having five faces. The first is "Om". The second is "Bhur-bhuvah-svah". The third is. "Tat-savitur Vareñyaṃ". The fourth is "Bhargo Devasya Dhīmahi". The fifth is "Dhiyo Yonah Prachodayāt". Gayatri represents in these five faces the five prāñas (life forces). Gayatri is the protector of the five prāñas in man. “Gāyantaṃ trāyate iti Gayatri” -- Because it protects the one who recites it, it is called Gayatri. When Gayatri acts as protector of the life-forces, she is known as Savitri. Savitri is known in the sciptural story as the devoted wife who brought back to life her husband, Sathyavan. Savitri is the presiding deity of the five prāñas. She protects those who lead a life of Truth. This is the inner meaning.
When one's intelligence and intuition are developed by the recitation of the mantra, the activating deity is Gayatri. When the life-forces are protected, the guardian deity is called Savitri. When one's speech is protected, the deity is called Saraswati. Because of the protective roles of Savithri, Saraswati and Gayatri, in relation to life, speech and the intellect, Gayatri is described as "Sarva-devatā-swarūpiñi"--- the embodiment of all goddesses.
[‘Sathya Sai Speaks’ , vol 16.06: March, 17, 1983]
The Gayatri has three parts: 1.Praise, 2.Meditation, and 3.Prayer. First, the Divine is praised, then it is meditated upon in reverence and lastly, an appeal is made to the Divine to dispel the darkness of ignorance and to awaken and strengthen the intellect. Dhīmahi  is related to the meditative aspect. Dhīyo Yonah Prachodayāt relates to the aspect of prayer. Chanting of the Gayatri Mantra purifies the mind and confers devotion, detachment and wisdom.
[‘Sathya Sai Speaks’, vol 33.04: Feb, 10, 2000]

Sri Sathya Sai Baba - Universality of Gayatri Mantra


Om Bhur Bhuvaḥ Swaḥ
Tat-savitur Vareñyaṃ
Bhargo Devasya Dheemahi
Dhiyo Yonaḥ Prachodayāt

For every kind of power, proofs may be sought by direct perception or by the process of inference. Men sought to find out by what direct proof they could experience this transcendental power. They found the proof in the Sun. Without the Sun there will be no light at all. Nor is that all. All activities will come to a standstill. In this world hydrogen is essential for the growth of plants and of living beings. The Sun's primary components are hydrogen and helium. Without hydrogen and helium, the world cannot survive. Hence, the ancients concluded that the Sun was the visible proof (of a transcendental power). They also found some subtle secrets about the Sun. Hence, they adored the Sun as the principal deity in the Gayatri mantra. “Dhiyo yonah Prachodayāt” - May the Sun illumine our intellects in the same way he sheds his effulgence. This is the prayer addressed to the Sun in the Gayatri mantra. In this way, they came to regard the Gayatri mantra as the mother of the Vedas.
[‘Sathya Sai Speaks’, vol 24.08: May, 21, 1991]
The earliest finding of the seekers was that the Sun was the most important factor in determining the daily life of man and providing the basic requirements for living. Life would be impossible without the Sun for man, beast, bird or plant. The Sun was regarded as the source of all energy and responsible for birth, growth and destruction of all things in creation. It was for this reason that Sage Viswamitra glorified the Sun God (Savitr) in the Gayatri mantra.
[‘Sathya Sai Speaks’, vol 19.4: March, 8, 1986]
Repeat the Gayatri - it is a universal prayer. It has three parts, meditation on the glory of God as the illumination immanent in the three worlds - upper, middle and lower (Om Bhur Bhuva Swah; Tat Savitur Vareñyam); it has smaraña or picturisation of the Grace (Bhargo Devasya Dhīmahi) and prārthanā, prayer for compassion for the sake of liberation, through awakening of intelligence that pervades entire universe, not to any particular name or form of that intelligence; and so, all can use it and be saved by it. There can be no fanaticism, no hatred, no rivalry, if the Gayatri is adhered to, its pious repetition will clarify the passions and promote love.
[‘Sathya Sai Speaks’, vol 07.37: October, 13, 1967]

Sri Sathya Sai Baba - Who is Mother Gayatri


Om Bhur Bhuvaḥ Swaḥ
Tat-savitur Vareñyaṃ
Bhargo Devasya Dheemahi
Dhiyo Yonaḥ Prachodayāt
Gayatri is the Mother of all scriptures (Vedas). She is present, wherever Her name is chanted. She is very powerful. The One who nourishes the individual being is Gayatri. She bestows pure thoughts on anyone who worships Her. She is the embodiment of all Goddesses. Our very breath is Gayatri, our faith in existence is Gayatri. Gayatri has five faces, they are the five life principles. She has nine descriptions, they are ‘Om, Bhur, Bhuvah, Swah, Tat, Savitur, Vareñyaṃ, Bhargo, Devasya’. Mother Gayatri nourishes and protects every being and she channelizes our senses in the proper direction. ‘Dhīmahi’ means meditation. We pray to her to inspire us with good intelligence. ‘Dhīyo Yonah Prachodayāt’ - We beseech her to bestow on us everything we need. Thus Gayatri is a complete prayer for protection, nourishment and finally, liberation.
[‘My Dear Students’, Vol 3, Ch 2, Mar 19, 1998]
Gayatri is the mother of the Vedas (Gayatri Chandhasam matha) Gayatri, however, has three names: Gayatri, Savitri, and Saraswathi. These three are present in everyone. Gayatri represents the senses; it is the master of the senses. Savitri is the master of Prana (Life Force). Many Indians are familiar with the story of Savitri, who brought back to life her dead husband, Sathyavan. Savitri signifies truth. Saraswathi is the presiding deity of speech (vaak). The three represent purity in thought, word, and deed (thrikarana shuddhi). Although Gayatri has three names, all three are in each of us as the senses (Gayatri), the power of speech (Saraswathi), and the life force (Savitri).
[‘Sathya Sai Speaks’, vol 28.22: August, 23, 1995]

Sri Sathya Sai Baba - What is the Gayatri Mantra


Om Bhur Bhuvaḥ Swaḥ
Tat-savitur Vareñyaṃ
Bhargo Devasya Dheemahi
Dhiyo Yonaḥ Prachodayāt
The Gayatri is a universal prayer enshrined in the Vedas. It is addressed to the Immanent and Transcendent Divine which has been given the name 'Savita,' meaning 'that from which all this is born.' The Gayatri may be considered as having three parts - (i) Adoration (ii) Meditation (iii) Prayer. First the Divine is praised, then It is meditated upon in reverence and finally an appeal is made to the Divine to awaken and strengthen the intellect, the discriminating faculty of man.
The Gayatri is considered as the essence of the Vedas. Veda means knowledge, and this prayer fosters and sharpens the knowledge-yielding faculty. As a matter of fact the four core-declarations enshrined in the four Vedas are implied in this Gayatri mantra.
[‘Sathya Sai Speaks’, vol 13.34: June, 20, 1977]
The Gayatri Mantra is a sacred chant that demonstrates the unity that underlies manifoldness in creation. It is through the recognition of this unity that we can understand the multiplicity. Clay is one and the same thing, though pots of different shapes and sizes can be made from it. Gold is one, though gold ornaments can be multifarious. The Atma is one, though the embodied forms in which it resides may be many. Whatever the colour of the cow, the milk is always white.
[‘Sathya Sai Speaks’, vol 16.6:  March, 17, 1983]

Sage Vishvamitra & the Gayatri Mantra

Vishwamitra ,who was king of India, once went for hunting in the Himalayan jungles with a big retinue of solders. His troops felt hungry & weak after the long hunt was over. While returning back they a saw a hermit & on enquiry found it to be that of Brahmarshi, Vashishta, a sage of cosmic consciousness. The king met with the Sage & saluted him. Finding them fatigued & run down, the Sage asked the King if he could be of some help. The king said his troops were hungry & were in need of rest as they had no food since the time they entered the dense jungle in the morning. The Sage immediately called Kamadhenu, the cow of plenty & asked her to feed the troops & the King. The wish-cow produced the food by her mere will in a plentiful manner. She fed them all to their hearts content.
The King was amazed at the wish-fulfilling powers of the Cow. He requested the Sage to give the cow to him, as he had a large population to feed & this cow would be useful to him for the benefit of the people of his country. He argued that its utility remained highly underutilised as it served just a handful of persons living in the hermitage. The King was prepared to give in exchange a thousand cows & take the cow of plenty with him.
The Sage told him that this cow was specially given to him by God & he cannot give it even in exchange of king’s whole kingdom. He told him emphatically that only those who have realised Truth (Brahman in Vedanta) are given this wish fulfilling cow. At the Sage’s refusal, the King got enraged & stated that he was insulted as no one could refuse a king’s request. He ordered that the cow be removed by force. As soon as troops tried to seize the cow, thousands of celestial men appeared with their weapons & the troops were forced out. Thereafter, with uncontrolled anger, Visvamitra began the fight with Sage Vashista, who held his bramah-danda (monks staff) in the forefront & the challenge started. All the arrows & weapons fired by Vishwamitra, were destroyed by the monk’s staff & he was left defenceless. The bramah- danda was now ready to strike the king, who immediately realised that time was over for him. Finally, king realising the power of a Brahmarshi,   sought for forgiveness. Being kind & compassionate, Sage Vashista withdrew & forgave him.
The king still felt insulted & secretly he vowed revenge. For this he must have more powers than the Sage. The kingdom, rulership, wealth & power & his vast possessions, were nothing before the effulgence (tejas) of a Brahmarshi. It dawned on him that nothing was greater than the knowledge of Truth. He renounced queen, sons & kingdom & retired to Himalayas to practise tapasya. He was in an unchartered area knowing nothing about yoga, pranayama, meditation & austerity. Bereft of comforts, he felt despondent & miserable. But his ego prevented him from seeking guidance of Sage Vashista.  It was the powerful urge to succeed & acquire knowledge that sustained him.
Vishvamitra proceeded to practise meditation intensely on Cosmic self, like Lord Shiva, in the serene upper reaches of Himalayas & never gave up. He was able to separate mind stuff from the body & developed a deep sense of detachment. Ultimately he stilled his thoughts & the yogic fire burst forth in him touching upper spheres of consciousness. Indira, the celestial God, panicked as Vishwamitra could be a threat to his throne. He sent a celestial beauty, Menaka to disrupt his tapasys. Visvamitra was bewitched by her smile & charm which disturbed his tapasya. He lived with Menaka for some time in the forest & begot her a daughter who is well know in Sanskrit literature as Shakuntala. After her, successful mission, Menaka returned to her celestial abode. The daughter was brought up in the forest by a sage called Kanva.
Vishvamitra now fully realised the power of Maya & he moved to another forest. He now renounced food, drink & was determined to achieve the goal. He is reported to have stood on one leg with uplifted arms, & meditated in this way on Brahman for a number of years. He reached the three worlds by austerity & yogic power. Indira again panicked, & this time he sent Rambha, another celestial nymph, to spoil his penance. No doubt Visvamitra’s meditation was shaken, but he realised his earlier mistake when he fell because of lust. Knowing that she had come to create a problem, he opened his eyes & uttered a curse that turned her into a rock. True Knowledge was now dawning upon him: he realized that earlier it was lust that disturbed him in penance, now it was anger. Although he now understood that spiritual path is like walking on razor’s edge, he vowed to push ahead with greater zeal & determination. He moved on to a new Himalayan peak, where he held his breath for a number of years & acquired great spiritual powers.
King Trishanku was ruler of India at that time. He was in the midst of organizing, a great yagnya, to help him to ascend to savrgalokain the human form. Sage Vashista, who was his ‘kul-guru’, refused to conduct the fire sacrifice as it was against divine law. He approached Vishvamitra, who was only willing to be the chief priest as it was a godsend opportunity to display his yogic powers. The yagnya was successfully performed in the king’s palace & by Vishvamitra’s spiritual powers the king was sent to savargaloka in the human form. Indira & other celestials finding Trishanku entering heaven in earthly body, sent him back. With legs up & head down, Trishanku came crashing down to earth & cried for help saying ”Vishvamiter, Vishvamiter please protect me”. With enormous yogic power, Sage Vishvamitra stopped his fall from heaven & created a new celestial world for him. Trishanku even today is shinning as a star in the sky. To us, today, Trishanku means that one is neither here nor there (latka hua manush).
This was one more fall for Vishvamitra & he lost all his yogic powers as he used them for ulterior gain. Because his spirit was indomitable, he took a final decision not to give up meditation. He selected a new place in the Himalayas & new effort began earnestly. Seasons rotated; years passed. He sat motionless fixing his gaze between the eyebrows. This time his yogic power was so intense that it woke up Brahma in Satyaloka. Brahma told him that he had attained great yogic powers of a maharshi. But to become a Brahmarsi, Sage Vashista must bless him. He was asked to go & meet him.
Sage Vishvamitra was frustrated as he could not tolerate to seek blessings of his foe. He felt that so long as Sage Vashista was alive, he could never become a Brahmarshi. Therefore he must kill him. Vishvamitra collected a big rock & went to the hermitage of Sage Vashista at midnight. He waited for the time the Sage would come out to the river for morning meditations, when he would hurl the big rock on his head. As he was standing close to the door of the hermitage, he heard Vashista speaking to his wife, Arundhati that Visvamitra was a great man & he was close to attaining the status of a Brahmarshi. But this could happen only if Vashista comes to meet him. “But will you bless him?” Arundhati asked. ”Of course, I will”, said Sage Vashishta.
On hearing this Visvamitra felt ashamed of himself, rushed inside & prostrated himself before Sage Vashista. “Now you have become a Bramarshi. You have conquered anger, lust, greed, attachment & arrogance one by one. The last barrier you crossed was jealousy. You have also shown that human spirit is invincible & accepts no defeat”, said Vashishta  to Visvamitra. Thereafter as Vashista touched his brow centre, Visvamitra’s third eye opened &  he saw the seven rhythms with which cosmos was created. The sacred Gayatri Mantra, was revealed to him at that time, thus:
The shorter form of the Gayatri is practiced far more commonly:

“OM BUHR, BHUVA, SWAHA
OM TAT SAVITUR VARENYAM
BHARGO DEVASYA DHEEMAHI
DHIYO YONAHA PRACHODAYAT”

We meditate on the glory of the Creator;
Who has created the Universe;
Who is worthy of Worship;
Who is the embodiment of Knowledge and Light;
Who is the remover of Sin and Ignorance;
May He open our hearts and enlighten our Intellect.

The longer version is more profound.
“OM BHUR, OM BHUVAHA, OM SWAHA,
OM MAHAHA, OM JANAHA, OM TAPAHA, OM SATYAM
OM TAT SAVITUR VARENYAM
BHARGO DEVASYA DHEEMAHI

DHIYO YONAHA PRACHODAYAT”

Gayatri Mantra

OM BHURBHUVAHA SWAHA TATA SAVITUR VARENYAM
BHARGODEVASYA DHIMAHI DHIYO YO NAHA PRACHODYAT
Om has three Hindi words. Aa, Uu and Ma.
Aa is meant for Aakaar from which three names of God are built, Viraat, Agni, and Vishwadi
Uu = uukar from which Hirannyagarbha, Vayu and Tejas names occur and
Ma = makaar from which Ishwar, Aditya and Praajyan aadi, holy names of God occur.
Rigveda mantra 1/164/46 says God is one but His names are several. But here OM the holy name of God is only being explained.
VIRAAT = Viraat word is made from dhatu 'Rajrideeptau' i.e., manifest. Therefore Viraat means He who manifests the universe. As God manifests the universe, thus Viraat is the name of God. Rigveda mandal 10, sukta 129 states that like potter makes pot from clay, similarly God creates universe from non-alive matter prakriti. Prakriti is unseen matter. From unseen matter, the whole universe is created in the visible form. Science also says that matter is never destroyed but changes its form. Suppose a paper is burnt, paper changes its form into ashes. Then ashes are crushed and thrown in air. At this moment, the paper changed into ashes becomes invisible but was never destroyed. Similarly the whole universe at the time of final destruction is turned into prakriti i.e., into unseen form.
AGNI = From dhatu, "ANCHU GATI POOJANAYOHO" the word "AGNI is made. Its meaning is: He who is a form of wisdom. "SARVAJAYEN" i.e. Omniscient. That is, knows each and every atom of universe and even beyond universe. He who is to be known, to be gained and is worshipful. So Agni is the name of God.
VISHWA = Vishwa word is made from dhatu, "VISHPRAVESHANE". Its meaning is He in whom the universe is entering or He who is entering the universe. So being omnipresent, Vishwa is the name of God.
HIRANNYAGARBHA = i.e., " JYOTIRVAYIHIRANYAM". Its meaning is, who is the base of all sun, etc., luminous lokas or He who is the living place of all luminous lokas. 
VAYU = from dhatu, "VA GATIGANDHANYOHO", vayu word is made. Its meaning is He who holds, gives life and destroys and is the mightiest amongst all. So the name of God is Vayu. 

TEJ = from dhatu, "TIJA NISHANE", the word Tej is made meaning He who is self made and self-enlightened and gives light to sun, moon, stars etc. God does not take light from anywhere but gives light to sun, moon, stars, etc. so the unbroken, unobstructed/unproduced and eternal form of light is Almighty God and not sun, moon etc. So the name of God is Tej.
ISHWAR = from dhatu, "ISH ASHWERIYE", the word Ishwar is made. Its meaning is whose knowledge is thoughtful and true and He who has unlimited wealth, fortune and glory etc. Therefore the name of God is Ishwar. Here it is not out of place to mention that soul (man/woman) has limited qualities and are dependent whereas God is independent and has unlimited qualities that is why He is God.
ADITYA = from dhatu, "DO AVAKHANDANE", Aditya word is made. Its meaning is the one who cannot be broken into pieces and thus cannot be destroyed. So God's name is Aditya.

PRAJAYEN (PRAGYA) = from dhatu, "JYEN AVABODHANE", Prajayen word is made meaning whose wisdom is totally without any misunderstanding and thus he who knows every matter and behavior of whole universe without misunderstanding. So God's name is Prajayen. So here also it is not out of place to mention that illusion can never attack on God and God is totally free from illusion.
BHUHU = "BHUHU ITI VAYEE PRANAHA" i.e., He who is the base of lives of universe, is most beloved, even more than Prann i.e., breath. So Bhuhu is the name of God. 
BHUVAHA= "BHUVAHA ITI APANAHA" i.e., He who is totally free from any sorrow, and the soul removes his own all sorrows after coming in contact with Him. So the name of God is Bhuvaha.

SWAHA = i.e., "SWAHA ITI VYANAHE" who is omnipresent in the universe and is holding the same. So the name of God is Swaha.
SAVITUHU = He who creates the universe. So the name of God is Savituhu. 
DEVSYA= who gives all pleasure/merriment, so the name of God is Dev. 
VARENNYAM = He who is the most supreme and acceptable. God is most supreme and acceptable for worship. 
BHARGAHA = the purest entity (though God is formless, but finding no suitable English word of Sanskrit word, "SHUDH SWARUPAM" the word entity has been used.) 
TAT = i.e., the God i.e., of the purest entity. 
DHIMAHI = i.e., we must hold (sort of meditation) because 
YAHA = the God
NAHA = our,
DHIYAHA = mind(i.e., in our minds) 
PRACHODYAT = by inspiration (fulfil the mind with wisdom) 
MEANING 
"We meditate the God who is the base of lives' of universe, totally free from any sorrow, omnipresent, creates the universe, gives all pleasure/merriment, most supreme and acceptable, purest entity; May the God enlighten our minds with wisdom by His inspiration". 

Here it is not out of place to mention that idea of a (one) Ved mantra is based on ideas of several Ved mantras.
So in the above Gayatri mantra, there are three things:
Bhuhu, Bhuvaha, Swaha, Savituhu, Bhargaha, Devsya are some qualities amongst unlimited qualities of God. These are called Stuti i.e., to say about God with His real qualities and not self made etc.
Dhimahi means meditation i.e., one should always sit in meditation and do hard and pious deeds for which he will have to study Vedas in full, while discharging moral duties towards family and nation. 
Dhiyo Yo Naha Prachodyat. It is a prayer to God explanation of which is cited above.
