Sage Vashitha performed the first Sadhana of Gau Gayatri. Chanting the Gau Gayatri mantra yields the rich milk of Kamdhenu and she bestows success, riches, power, love and fulfillment of all desires.
Gayatri is the ‘Blessed Mother’ of Vedas. There is no milk superior to cow’s milk. Even so there is no Mantra superior to Gayatri. As Omkara or Pranava is for Sannyasins, so is Gayatri for Brahmacharis and householders. The fruits that are attained by meditation on Omkara can be attained by meditation on Gayatri. The secret lore of the Upanishads is the essence of four Vedas, while Gayatri with the three Vyahritis is the essence of the Upanishads.
Gayatri is the mother of the Vedas and the destroyer of sins. There is nothing more purifying on the earth as well as in the heaven than the Gayatri. The Japa of Gayatri brings the same fruit as the recitation of all the four Vedas together with the Angas. This single Mantra, if repeated three times a day, brings good (Kalyan or Moksha). It is the Mantra of the Vedas. It destroys sins. It bestows splendid health, beauty, strength, vigour, vitality and magnetic aura in the face (Brahmic effulgence).
Gayatri destroys the three kinds of Taapa or pain. Gayatri bestows the four kinds of Purushartha viz., Dharma (righteousness), Artha (wealth), Kama (desired objects) and Moksha (liberation or freedom). It destroys the three Granthis or knots of ignorance, Avidya, Kama and Karma. Gayatri purifies the mind. Gayatri bestows Ashta Siddhis. Gayatri makes a man powerful and highly intelligent. Gayatri eventually gives liberation or emancipation from the wheel of births and deaths.
The mind is purified by constant worship. It is filled with good and pure thoughts. Repetition of worship strengthens the good Samskaras. “As a man thinks, that he becomes.” This is the psychological law. The mind of a man who trains himself in thinking good, holy thoughts, develops a tendency to think of good thoughts. His character is moulded and transformed by continued good thoughts. When the mind thinks of the image of Gayatri during worship, the mental substance actually assumes the form of the image. The impression of the object is left in the mind. This is called Samskara. When the act is repeated very often, the Samskaras gain strength by repetition, and a tendency or habit is formed in the mind. He who entertains thoughts of Divinity becomes transformed actually into the Divinity himself by constant thinking and meditation. His Bhava or disposition is purified and divinised. The meditator and the meditated, the worshipper and the worshipped, the thinker and the thought become one and the same. This is Samadhi. This is the fruit of worship or Upasana.
