The seeker of the integral Yoga begins with the understanding that there is an omnipresent reality which has a transcendent Spirit as the source of all, yet beyond all the manifested forms of the universe, a universal form of manifestation which partakes of the reality as it is a manifestation of that Spirit, and individual forms which participate in the universal manifestation while themselves partaking of the nature of the Spirit. The integral Yoga does not accept, therefore, any one-sided realization which denies or minimizes the reality of either the Transcendent or the Universal; rather, they are to be integrated together.
Sri Aurobindo observes: “If the highest height of spiritual experience, the sheer summit of all realisation is the absolute union of the soul with the Transcendent who exceeds the individual and the universe, the widest scope of that union is the discovery of that very Transcendent as the source, support, continent, informing and constituent spirit and substance of both these manifesting powers of the divine Essence and the divine Nature. Whatever the path, this must be for him the goal. The Yoga of Action also is not fulfilled, is not absolute, is not victoriously complete until the seeker has felt and lives in his essential and integral oneness with the Supreme….The Yoga of devotion too is complete only when the lover and the Beloved are unified and difference is abolished in the ecstasy of a divine oneness, and yet in the mystery of this unification there is the sole existence of the Beloved but no extinction or absorption of the lover. It is the highest unity which is the express direction of the path of knowledge, the call to absolute oneness is its impulse, the experience of it its magnet: but it is this very highest unity which takes as its field of manifestation in him the largest possible cosmic wideness. Obeying the necessity to withdraw successively from the practical egoism of our triple nature and its fundamental ego-sense, we come to the realisation of the spirit, the self, the lord of this individual human manifestation, but our knowledge is not integral if we do not make this self in the individual one with the cosmic spirit and find their greater reality above in an inexpressible but not unknowable Transcendence. That Jiva, possessed of himself, must give himself up into the being of the Divine. The self of the man must be made one with the Self of all; the self of the finite individual must pour itself into the boundless finite and that cosmic spirit must be exceeded in the transcendent Infinite.”
