To listen to music or to sing a chant is to do something that has no practical purpose; it is just celebration and praise; it is just tasting the joy and beauty of life, the glory of God.

A disciple suddenly discovered the richness of fecundity of emptiness -- the realization that everything is impermanent, unsatisfactory, and empty of self. In this mood of divine emptiness, he sat in joy under a tree, when suddenly flowers began to fall all around him.
And the angels whispered, "But I haven't uttered a word about emptiness."
"True," the angels replied. "You have not spoken of emptiness, we have not heard of emptiness. This is true emptiness." And the showers of blossoms continued to fall.
