One might ask: How can the music of ancient times be kept pure, as there is always a tendency in human nature to alter things? It was always difficult for the human race to change religion; anything else might be changed, but there was one thing that was always kept, and that was religion. In the religion of the Hindus one aspect was music; it was called Sama Veda. In the Western world there came a time when translations were made of the Vedas, but there is a part of them of which the translation is not to be found: it is of that Veda. The reason is that, being musical, this Sama Veda could not well be regarded as being language.
