Sri Chinmoy: Heaven means the higher worlds in this case. There are seven higher worlds and seven lower worlds. Each world has a music of its own and a note of its own. The higher worlds have a music that awakens us, inspires us, illumines us, perfects us and fulfils us. The music of the higher worlds constantly comes to us as the harbinger of the highest Height, whereas the music of the lower worlds naturally comes to us as a messenger of destruction.
It is not only the higher and lower worlds that have a music of their own; each individual has his music, each movement has music, each action has music. Each time we breathe in and breathe out there is music. When we don’t pay attention to the inner depth of the action, we don’t hear the music. If we do pay adequate attention to each action, then inside the very depth of that action we are bound to hear music. Unless we hear music inside each action, the action is lifeless.
