Can anyone fail to see this who looks into the essential nature of love? What is loving ourselves alone, really, and not loving someone else who loves us in return? This is more fragmentation than union. Love’s union depends on mutuality, and there is no mutuality within ourselves alone. If we think there is, it is because we are imagining some mutuality in others.
We can see from this that divine love cannot fail to be and to be manifested in others whom it loves and who love it. If this is characteristic of all love, it must be supremely characteristic, infinitely characteristic, of love itself.
In regard to God, loving and being loved in return are not possible in the case of others who have some share of infinity or anything of the essence and life of intrinsic love or of Divinity. If there were within them any share of infinity or anything of the essence and life of intrinsic love—of Divinity, that is—it would not be others who would be loving God. He would be loving himself. What is infinite or divine is unique. If it were in others, it would still be itself; and it would be pure love for itself, of which there cannot be the slightest trace in God. This is absolutely opposite to the divine essence. For love to be mutual, then, it needs to be a love for others in whom there is nothing of intrinsic Divinity; and we will see below (Sections 55, 305) that it is a love for others who were created by Divinity.
For this to happen, though, there must be an infinite wisdom that is at one with infinite love. That is, there must be the divine love of divine wisdom and the divine wisdom of divine love discussed above (Sections 34–39).
