In the psychic being one gets the sense of oneness by psychic sympathy, but not any unification, for the psychic is the individual soul and must unify itself with the Divine before it can through the Divine unify with others. In spiritual realisation there are two quite opposite forms—one in which one withdraws from all outer things including all material beings in the world to merge in the Divine and one in which one feels the Self or the Divine in all and through that realisation attains to a universal oneness.
… the will, the aspiration is ours because it is his will in us. At first, while there is still insistence on our own personality, it only reflects that, but becomes more and more indistinguishable from it, less personal and eventually it loses all shade of separateness, because the will in us has grown identical with the divine Tapas, the action of the divine Shakti.
The psychic being stands behind the heart supporting the mind, life and body. In the psychic transformation there are three main elements:
It is quite possible for the psychic transformation to take one beyond the individual into the cosmic. Even the occult opening establishes a connection with the cosmic mind, cosmic vital, cosmic physical. The psychic realises the contact with all existence, the oneness of the Self, the universal love and other realisations which lead to the cosmic consciousness.
The individual …. As he develops, he moves towards a spiritual freedom, but this freedom is not something entirely separate from all-existence; it has a solidarity with it because that too is the self, the same spirit. As he moves towards spiritual freedom, he moves also towards spiritual oneness. The spiritually realised, the liberated man is preoccupied, says the Gita, with the good of all beings;
Unity will be the law, difference will be simply for the various enjoyment of that unity. Neither descending again into that plane of division which clings to the separation of the ego-sense nor attached to an exclusive seeking for pure identity which cannot have to do with any play of difference, we shall embrace and reconcile the two poles of being where they meet in the infinity of the Highest.
In this self-development the soul finds that it has accomplished on this line the object of the whole integral Yoga, union with the Supreme in its self and in its universalised individuality. So long as he remains in the world-existence, this perfection must radiate out from him,—for that is the necessity of his oneness with the universe and its beings,—in an influence and action which help all around who are capable of it to rise to or advance towards the same perfection, and for the rest in an influence and action which help, ….
… thus to be universally in the fullness and freedom of one's universality, one must be also transcendentally. The spiritual fullness of the being is eternity…. To transcend, to exceed consciousness of body, not to be held in the body or by the body, to hold the body only as an instrument, a minor outward formation of self, is a first condition of divine living. Not to be a mind subject to ignorance and restriction of consciousness, to transcend mind and handle it as an instrument, to control it as a surface formation of self, is a second condition. To be by the self and spirit, not to depend upon life, not to be identified with it, to transcend it and control and use it as an expression and instrumentation of the self, is a third condition.
Even the bodily life does not possess its own full being in its own kind if the consciousness does not exceed the body and feel its physical oneness with all material existence; the vital life does not possess its own full living in its own kind if the consciousness does not exceed the restricted play of an individual vitality and feel the universal life as its own and its oneness with all life. The mentality is not a full conscious existence or activity in its own kind if one does not exceed the individual mental limits and feel a oneness with universal Mind and with all minds and enjoy one's integrality of consciousness fulfilled in their wealth of difference. <ref>http://incarnateword.in/cwsa/22/the-divine-life#p14</ref>
