“The spiritual evolution obeys the logic of a successive unfolding; it can take a new decisive main step only when the previous main step has been sufficiently conquered: even if certain minor stages can be swallowed up or leaped over by a rapid and brusque ascension, the consciousness has to turn back to assure itself that the ground passed over is securely annexed to the new condition.” Sri Aurobindo looks at this evolution through the lens of time. The first stages, the emergence out of the Inconscience into physical consciousness, takes many millenia. The emergence thereafter of the life-consciousness occurs over further millenia, although substantially faster than the first stage. With the advent of mind, further stages develop ever more swiftly as there is more active awareness and participation in the process now possible. With the development of the psychic consciousness and spiritual focus, the next stages of development can move ever more swiftly.
Sri Aurobindo makes it clear that it is a question of the pace of development, not an over-passing of the steps, that comes up with the spiritual focus. “It is true that the conquest of the Spirit supposes the execution in one life or a few lives of a process that in the ordinary course of Nature would involve a slow and uncertain procedure of centuries or even of millenniums: but this is a question of the speed with which the steps are traversed; a greater or concentrated speed does not eliminate the steps themselves or the necessity of their successive surmounting. The increased rapidity is possibly only because the conscious participation of the inner being is there and the power of the Supernature is already at work in the half-transformed lower nature, so that the steps which would otherwise have had to be taken tentatively in the night of Inconscience or Ignorance can now be taken in an increasing light and power of Knowledge.”
What may appear to be a miraculous change in a particular life has been patiently prepared and developed behind the scenes by this action of Nature, and the sureness of the speed speaks to the intense and exhaustive preparation that has gone before.
