Supreme pure consciousness is Parabrahm, the impersonal Godhead. This transcendental consciousness as power is Mother. She is known as Gaayatree. She is the primal cause of everything that was, that is, and that will be. When she manifested her Tri-Gun or three qualities, known as Sattwa (poise), Rajas ( passion), and Tamas (stupor), these three qualities, possessing the pure consciousness (Parabrahman) took three forms known as Brahmaa, Vishnu and Shiv. Brahmaa was possessed by Rajas, Vishnu by Sattwa, and Shiv by Tamas Gun. Gaayatree was worshipped by the Trinity as The Mother. When Brahmaa, Vishnu and Shiv were just children, Gaayatree Devee put them into the cradle of Void (Aakaash) that was hung by the chains of the four Ved (wisdom) and with Om lullaby. She put them to sleep. Seeing that her children possessed by Gun were sleeping, Devee disappeared.

After a long time, the Tri-Moorti got up and began crying. They grew up and were wandering in Void by the power of the Gun and then they thought of finding their Mother. They sat in meditation for a long time. As the fire of their austerity was scorching the universe, the Universal Mother, being compassionate, decided to appear before them. Even though She is all-pervasive, still for her Divine Leelaa (sport), she manifested her Divine form.

She was the most beautiful Mother, she wore a red Saaree, garlands dangled round her neck and her face was like the Full Moon. She had three eyes and her forehead carried a round mark of red powder. She had eight arms holding lotuses, mace, conch, and rings, bangles and many shining rings, jewels and ornaments, all of which were Divine (A-Praakritik)

She came running for her children and perspiration was dropping from her face like pearls. She hurried to her children and called them by their names as Brahmaa, Vishnu and Shiv. The Tri-Moorti ran to their mother, who kissed and caressed them again and again. Holding them in her arms, she said :

"O Divine Children, I made you undergo this great agony of separation. I should have come to you long before. I just wanted you to gain powers of Creation, Preservation and Dissolution through austerity, so that the souls who partake their role in this cosmic Leelaa should see the ideal of austerity and penance shown by you three. I was always with you; within yourselves by my grace, then I took a transcendental form also so that the soul thereafter might worship my Divine form as the Divine Mother Gaayatree. I shall be pleased with their worship and confer on them all prosperity and Bhakti. Let Brahmaa, by the Rajas (passion and activity) Create; and Vishnu, by the quality of Sattwa (equilibrium) Maintain and Preserve, and let Shiv, by Tamas (destruction) bring Dissolution of this Universe at the end of cycles. Pray to me during the times of confusion and difficulty for guidance.

Saying thus, the most blessed Mother disappeared. This shows that Gaayatree is Ved Maataa or Mother of the Ved, ie sources of Divine wisdom. She is the inseparable power of Par Brahm, the Supreme pure consciousness.
