There is a well-known legend of the life of Moses which tells how Moses heard a divine command on Mount Sinai in the words: "Musake!'- Moses hear, or Moses ponder - and the revelation that thus came to him was of tone and rhythm. He called it by the same name: musake. Words such as "music", or "musik" have come from that word. David, whose song and whose voice have been known for ages, gave his message to the world in the form of music. Orpheus of the Greek legends, the knower of the mystery of tone and rhythm, had through this knowledge power over the hidden forces of nature. The Hindu Goddess of learning, of knowledge, whose name is Sarasvati, is always pictured with the vina. What does this suggest? It suggests that all learning has its essence in music.
