They just is. The sun makes no conditions. It just are. The air has no conditions. It just is.
Human beings make conditions.
The reason we make conditions . . . We think it is in limited supply. Like eggs in a basket, we believe that love is very fragile, and once it's gone, there ain't no more. Of course, we don't think that way about anything else that just is. That is, of course, because we don't know that love is as plentiful and ever-present as the stars, the sun, the air and energy.
