The first necessity for the seeker is to cultivate an inner status of equality. Without this, the individual remains entirely subject to the push and pull of the dualities, seeking out those things which attract and avoiding those things which repel, without the detachment required for both inner reflection and a deeper understanding of the role and need of each of those elements. The cultivation of the state of equality is essential to overcome the bondage of the ego and achieve both the liberation of the spirit and the ability to act as a true conduit of the divine Will in the manifestation of the universal action.
Sri Aurobindo extrapolates on this: “…equality is the sign of unity with the Brahman, of becoming Brahman, of growing into an undisturbed spiritual poise of being in the Infinite. Its importance can hardly be exaggerated; for it is the sign of our having passed beyond the egoistic determinations of our nature, of our having conquered our enslaved response to the dualities, of our having transcended the shifting turmoil of the gunas, of our having entered into the calm and peace of liberation. Equality is a term of consciousness which brings into the whole of our being and nature the eternal tranquility of the Infinite. Moreover, it is the condition of a securely and perfectly divine action; the security and largeness of the cosmic action of the Infinite is based upon and never breaks down or forfeits its eternal tranquility. That too must be the character of the perfect spiritual action; to be equal and one to all things in spirit, understanding, mind, heart and natural consciousness,–even in the most physical consciousness,–and to make all their workings, whatever their outward adaptation to the thing to be done, always and imminuably full of the divine equality and calm must be its inmost principle. That may be said to be the passive or basic, the fundamental and receptive side of equality, but there is also an active and possessive side, an equal bliss which can only come when the peace of equality is founded and which is the beatific flower of its fullness.”
