Yes, there is no other way for this Love to take place than with both of "them" being present, (in) (t)here, each of them accepting their role.

Present, united, and independent.

"Here", where and when the pain of separation is the redemption of (re)union at the same time.

Oh, that expansion of love towards Love! That increasing force to link the "two" to one another, until the hidden unity becomes conscious.

Atoms contributing to the expansion of the whole human "element" to the range of Love-wisdom.

It is a really moving poem, Jack.
