The Universe is made of vibration. Music is sound vibration in harmony. By listening to the music and vibrational techniques of the ancients ones, we can "tune ourselves" and raise our consciousness. From this higher frequency we become able to manifest the visions that we desire and hold in our imaginations. It is a spiritual law and how the process of creation works. The Universe was created by sound. The book of Genesis says: "and God SAID, let there be light". Sound came first and the universe (God's creation/imagination/the light) came after the first sound.
I have learned many of the secrets of consciousness raising music from my meditation Teacher, Maestro Tulshi Sen. His teachings reveal the mystical nature of music and how it can be used to shape our consciousness and literally change our lives.
