It is axiomatic that one cannot become something foreign to oneself in essential nature. There are those who believe that God and human are different orders of existence, and thus, there is an everlasting gulf between them and thus, our only relation to God must be one of adoration and submission. There are others who recognize an evolutionary stairway of consciousness that continues to expand and widen until it encompasses the experience, standpoint and awareness of the entire universal creation and the Lord and Creator. This viewpoint holds that our existence is created by, and from, the nature of God and thus, we can indeed achieve the Divine Consciousness. It is this view which the Gita sets forth, and which Sri Aurobindo describes.
The process of the creation of the phenomenal world, and the meaning behind it, can be subject to some debate as well, but eventually, however one wants to explain it, the solution comes to taking on a new status of consciousness and dwelling in the Eternity, Infinity and Reality of the ultimate Divine awareness.
Sri Aurobindo amplifies these points: “The soul of man could not grow into the likeness of the Divine, if it were not in its secret essence imperishably one with the Divine and part and parcel of his divinity: it could not be or become immortal if it were merely a creature of mental, vital and physical Nature. All existence is a manifestation of eternal Spirit.”
“The Eternal puts all this movement forth as his self-creation.” “The Spirit is eternal and superior to all its manifestation. Nature, eternal without beginning in the Spirit, proceeds for ever with the rhythm of the cycles by unending act of creation and unconcluding act of cessation; the Soul too which takes on this or that form in Nature, is no less eternal than she…. Even while in Nature it follows the unceasing round of the cycles, it is, in the Eternal from which it proceeds into them, for ever raised above the terms of birth and death, and even in its apparent consciousness here it can become aware of that innate and constant transcendence.”
