The more superficially one studies Buddhism, the more it seems to differ from the Brahmanism in which it originated; the more profound our study, the more difficult it becomes to distinguish Buddhism from Brahmanism, or to say in what respects, if any, Buddhism is really unorthodox. The outstanding distinction lies in the fact that Buddhist doctrine is propounded by an apparently historical founder, understood to have lived and taught in the sixth century B.C. Beyond this there are only broad distinctions of emphasis. It is taken almost for granted that one must have abandoned the world if the Way is to be followed and the doctrine understood.... but nothing could be described as a 'social reform' or as a protest against the caste system. The repeated distinction of the 'true Brahman' from the mere Brahman by birth is one that had already been drawn again and again in the Brahmanical books.

The image of Shiva as Nataraj is indelibly stitched into the Indian imagination. How many various dances of Shiva are known to His worshippers. I cannot say. No doubt the root idea behind all of these dances is more or less one and the same, the manifestation of primal rhythmic energy. Whatever the origins of Shiva's dance, it became in time the clearest image of the activity of God which any art or religion can boast of.

Almost all that belongs to the common spiritual consciousness of Asia, the ambient in which its diversities are reconcilable, is of Indian origin in the Gupta period.
