Love is discovery of ourselves in others. Unconditional love is discovering ourselves in every one. Treating entire humanity as one.
There is no discrimination. There are no boundaries. The self is not tethered to a post. The self rises in an unbounded vast sky, finding own image on others.
And then the delight is in experiencing the recognition. I find myself in you, I recognize the part of you that is like me, I feel unlimited delight. I am I love, I feel love, I become love.
