A human being is part of a whole, called by us the "Universe", a part limited in time and space. We experience ourselves, our thoughts and feelings, as something separated from the rest -- a kind of optical delusion of our consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest us. Our task must be to free ourselves from this prison by widening our circles of compassion to embrace all living creatures and the whole of nature in its beauty.
The angels can know us more intimately and love us when we sing, and they are not asking that we sound like the Philharmonic. They ask us simply to sing because we are harmonic. We are symphonic and in these ways we can connect with the angelic world. I think and feel that the angels wait for us at every given moment. If we alternate song and silence, consciously, with burning attention, every rounded tone carves out the possibility to bridge heaven and earth, to live the material half of the angel.
