Sri Aurobindo pointedly notes the secret of spiritual realisation when he indicates “To know Vasudeva as all and live in that knowledge is the secret.” For someone starting out in the mental consciousness characterized by fragmentation, division and separation, this is not something that occurs instantly and completely, but rather, is something that grows as one experiences different aspects of the higher truth and as one establishes a foundation of seeing, knowing and experiencing that is based in that higher consciousness rather than in the mental framework.
One of the key experiences removes the seeker from being locked into the mental frame: “He knows him as the Self, immutable, continent of all as well as immanent in all things.” This experience transcends all forms and forces. “He draws back from the confused and perturbed whirl of the lower nature to dwell in the still and inalienable calm and light of the self-existent spirit.”
There is still the Eternal, beyond, ultimately transcendent and unmoved by anything that exists. But there is also “the divine Inhabitant in all things that are, the Lord in the heart of man, the secret Ishwara…” It is the goal of the seeker to unify his will with the divine Will, to unify his actions with the intent of the divine Action, and thus to act, not from a sense of a separated ego-personality, but as an expression of that divine Will in its own manifestation.
Through the constant experience of the divine Presence, there is a transformation in the way the seeker sees, thinks and acts. “Therefore too his whole inner existence comes into tune and harmony with the Infinite now self-revealed in all that lives or is within and around him and his whole outer existence turns into an exact instrumentation of the cosmic purpose.”
Everywhere he looks he sees the Divine. “Thus he arises through a limitless unfolding of knowledge and upward vision and aspiration to that to which he has turned with an all-compelling integrality….”
