What is this secret Oneness?
It is precisely the divine Presence.
Because the Divine is essentially one, and yet He has subdivided Himself apparently in all beings, and in this way recreated the primordial Oneness. And it is because of this divine Oneness—which, however, appears fragmented in beings—that the Unity is re-established in its essence. And when one becomes conscious of this, one has the joy of the consciousness of this Oneness. But those who are not conscious—what they miss is the joy of consciousness. But the fact remains the same.
Sri Aurobindo says: the Oneness exists; whether you are aware of it or not, it exists, in reality it makes no difference; but it makes a difference to you: if you are conscious, you have the joy; if you are not conscious, you miss this joy.
