Emptiness of Self
The expression of emptiness is love, because emptiness means "emptiness of self." When there is no self. there is no other. That duality is created by the idea of self, of I, of ego. When there's no self. there is a unity, a communion. And without the thought of "I'm loving someone," love becomes the natural expression of that oneness.
