Sri Aurobindo discusses the static “typal” action of life in relation to a possible “progressive” action in the human being. “it may be conceded that each type or pattern of consciousness and being in the body, once established, has to be faithful to the law of being of that type, to its own design and rule of nature. But it may also very well be that part of the law of the human type is its impulse towards self-exceeding, that the means for a conscious transition has been provided for among the spiritual powers of man; the possession of such a capacity may be a part of the plan on which the creative Energy has built him.”
While it is clear that up until now man has developed within the framework and capacities of his nature, we can see a line of progress whereby the powers of mentality, emotion, and action have been systematically developed, enhanced and subtilised. While this progress has not taken place in a straight line, and there have been obvious periods of retrogression and stagnation, yet, looking over the whole of human history and development, we can nevertheless see a pattern of development.
“This progress has not indeed carried the race beyond itself, into a self-exceeding, a transformation of the mental being. But that was not to be expected; for the action of evolutionary Nature in a type of being and consciousness is first to develop the type to its utmost capacity by just such a subtilisation and increasing complexity till it is ready for her bursting of the shell, the ripened decisive emergence, reversal, turning over of consciousness on itself that constitutes a new stage in the evolution.”
“If it is to be supposed that her next step is the spiritual and supramental being, the stress of spirituality in the race may be taken as a sign that that is Nature’s intention, the sign too of the capacity of man to operate in himself or aid her to operate the transition. If the appearance in animal being of a type similar in some respects to the ape-kind but already from the beginning endowed with the elements of humanity was the method of the human evolution, the appearance in the human being of a spiritual type resembling the mental-animal humanity but already with the stamp of the spiritual aspiration on it would be the obvious method of Nature for the evolutionary production of the spiritual and supramental being.”
