In its normal relationship to nature, the conscious being, what Sri Aurobindo calls Purusha, the Witness Consciousness, is essentially passive and subject to the action of nature. And the normal experience we have in life is that nature drives us whithersoever it will, and we essentially are under its control. This led, among some souls dissatisfied with this relationship, to the attempt to liberate the soul from nature, and the entire range of yogic, mystical and religious otherworldly experience.
One of the first liberating experiences in yoga is to step back from the action of nature and adopt the standpoint of the witness consciousness. Sri Aurobindo discusses this “If the Purusha in us becomes aware of itself as the Witness and stands back from Nature, that is the first step to the soul’s freedom; for it becomes detached, and it is possible then to know Nature and her processes and in all independence, since we are no longer involved in her works, to accept or not to accept, to make the sanction no longer automatic but free and effective; we can choose what she shall do or not do in us, or we can stand back altogether from her works and withdraw easily into the Self’s spiritual silence, or we can reject her present formations and rise to a spiritual level of existence and from there re-create our existence. The Purusha can cease to be subject, anisa, and become lord of its nature, isvara.”
This in fact represents one of the keys to the spiritual evolution in the individual. First, achieving the separation of the consciousness into Witness and Active Nature; and then later taking control of the Nature from that separated standpoint. In this wise, we are not bound to deny or disregard nature; but rather, we can take it up and transform it. This is a distinction of signal importance in the yogic path set forth by Sri Aurobindo as opposed to the traditional path of renunciation of nature.
In Sri Aurobindo’s yogic view, Purusha and Prakriti need not be irreconcilable opposites, but rather the passive and active, static and dynamic standpoints of one integral whole, the all-encompassing, all-containing, all-creating Brahman.
