The human being represents the development of a new power of consciousness for the earth-nature. This does not imply that at the present time all human individuals are able to fully manifest this power, but it is clear there is a continuum that puts all humanity on a level of its own, with the variances between individuals primarily one of intensity or magnitude of the manifestation of the power of the mind of reason. This evolutionary leap took place within the framework of physical matter and vital powers that define the animal kingdom. While animals are typal beings, tied to their habits and customs without enormous range of creativity or development, human beings have proven themselves capable of self-reflection and inner growth. At the same time, the development of the mental powers has resulted in a considerable amount of imbalance, as if humanity had not yet found its solid footing with these new powers. This is a sign that the evolutionary transition is not yet completed and that man is a transitional, not a final, typal being. There is more room for growth and development in humanity’s future.
Sri Aurobindo notes: “If the light that is being born increases, if the number of individuals who seek to realise the possibility in themselves and in the world grows large and they get nearer the right way, then the Spirit who is here in man, now a concealed divinity, a developing light and power, will descend more fully as the Avatar of a yet unseen and unguessed Godhead from above into the soul of mankind and into the great individualities in whom the light and power are the strongest. There will then be fulfilled the change that will prepare the transition of human life from its present limits into those larger and purer horizons; the earthly evolution will have taken its grand impetus upward and accomplished the revealing step in a divine progression of which the birth of thinking and aspiring man from the animal nature was only an obscure preparation and a far-off promise.”
