Everything harmonizes with me, which is harmonious to thee, O Universe. Nothing for me is too early or too late, which is in due time for thee. There is one light of the sun, though it is interrupted by walls, mountains and infinite other things. There is one common substance, though it is distributed among countless bodies which have their several qualities. There is one soul, though it is distributed among several natures and individual limitations. There is one intelligent soul, though it seems to be divided.
