When we look at it from the metaphysical point of view, we shall find that the realization and knowledge that science has today - and will ever have - that vibration is at the root of the whole creation, was a certainty to the ancient people; it was the basis of their whole science. They knew that that which has created, and which is holding, and in which is held the whole manifestation and the whole cosmos, is one power, and that is vibration. It is because of this that astrological science, which had much to do with the way human beings and different countries were influenced, also arose out of that science of vibration. Thus music, as a science, was known by them to have a great deal to do with the influence of the planets. And the continual moving and working of the planets, and their action upon the earth, were the basis of the Ragas on which their music was founded.
