Manifestation of Gayatri by Brahma

Brahma is the supreme divine creator of all. No sooner did the urge of creation arise in Brahma, a vibration was created which is known as Shakti (energy of power). This Shakti manifested as Jad (inanimate) and Chetan (animate) objects and creatures. The inanimate creation is governed by material nature (Prakriti) and animate creation is governed by Chitta Shakti which is known as Savitri.
It has been described in the scriptures that in the beginning of the creation a lotus flower rose up from Vishnu's Navel. Brahma the creator originated from this lotus flower. From, Savitri was created and through the union of Brahma and Savitri, all the four Vedas came into existence. Knowledge of all kinds originated from the Vedas and thereafter, Brahma created this material world comprised of the five basic elements. The secret behind this allegorical description is that from the interior or centre of the Uninvolved, Invariable, Absolute Divine Being, a lotus flower came into existence. According to the scriptures, in the beginning of the creation, the supreme absolute willed to get himself multiplied, "Ekoham Bahushyal". This willed vibration across from the focal point and blossomed in the form in the form of a lotus flower.
Brahma who is said to be born of lotus flower is one of the three basic manifestations of the Absolute Divinity - Brahma, Vishnu and Mahesh symbolizing creation. Nature and dissolution respectively. The first born of the triple divinity had to be Brahma, the creator, as creation proceeds nurture dissolution.
Brahma started his work and created two kinds of creation, Chaitanya (animate) and Jad (inanimate). All living beings having desire, consciousness and ego fall under Chaitanya creation. This is an independent creation which is known as Pranmaya Kosh (physical body) of the universe. Chaitanya (animate) element pervades the entire universe and is known as Pran. Ideas will and emotions are three attributes of Pran- Tatva which constitute the three coverings (bodies) of the soul -astral (Sukshma), casual (Karan) and physical (sthool). All living beings owe their consciousness and existence to this Pran- Tatva.
For creating Jad (inanimate) creation comprising matter, Brahma created five elements (Panchbhoot) viz, earth, water, air, fire and ether. The atoms of the entire material nature manifest as solid, liquid or gas. This vast expanse of nature in the form of rivers, mountains, earth etc is the play of atoms of these five elements. Physical bodies of all living beings are also constituted by these five elements of nature.
There is activity in both these creations. In Chaitanya creation it is seen in various activities in the form of ego, determination and inspiration. In Jad creation, the form color, shape etc of different objects are formed and dissolved on the basis of the vibrating energy. The basis of Jad creation is atom and of Chaitantya creation, conscious will. Both these bases are superbly subtle and powerful. They are indestructible and they simply change their forms.
In the emergence of Jad and Chaitan creations, Brahma's powers of Chetna (consciousness) and Padarth (matter) are functioning. Initially needs was felt for the power of will as, without it chaitanya could not manifest. In the absence of Chaitanya energy, none could have knowledge about matter and it would have remained without any use. The utility of matter is for the convenience of manifestation of Chaitanya. Therefore, Brahma initially created Chaitanya and discovered will for knowledge. In Puranic language it can be said that Vedas or knowledge manifested first of all. The energies of conscious will (Sankalpa) and matter (padartha) are two arms of Brahma by which the work of creation is accomplished. Since the former is animate (Chaitan), it is also described as Brahma's wife.
