Integration of Evolutionary Stages Throughout the Process

Sri Aurobindo addresses the objection that the dramatic differences between the different classes of manifestation mean that they cannot have evolved one out of the other. “But it must be observed that this ascent, this successive fixing in higher and higher principles, does not carry with it the abandonment of the lower grades, any more than a status of existence in the lower grades means the entire absence of the higher principles.” He continues: “for if the rudiments of the higher are present in the lower creation and the lower characters are taken up into the higher evolved being, that of itself constitutes an indubitable evolutionary process.”

The underlying necessity is for the lower principle, whether Matter initially, or Life or even Mind eventually to be able to be modified so that it can accomodate the working of the next evolutionary principle. “at that point a pressure from some superior plane where the new power is dominant may assist towards a more or less rapid and decisive transition by a bound or a series of bounds,–a slow, creeping, imperceptible or even occult action is followed by a run and an evolutionary saltus across the border. It is in some such way that the transition from the lower to the higher grades of consciousness seems to have been made in Nature.”
