The Relation between Buddhist and Hindu Tantra
Tantra literature began to appear in both the Buddhist and Hindu traditions of India in
approximately the third century CE. Precise dates, however, are unavailable and the two
traditions undoubtedly predated the appearance of their texts. Although the philosophical and
ethical contexts differ, nevertheless devotional practices, yoga exercises, and numerous
aspects of earlier matriarchal, tribal, and outcaste customs are prominent in each. For example,
both systems include visualization of multiarmed, multifaced figures, manipulation of subtle
energies through energy-nodes (Skt. chakras), veneration of women, use of bone ornaments
and musical instruments, imagery from cremation grounds and slaughterhouses, and
transformation of unclean bodily products. Thus, it is difficult to prove that one was the source
of a specific feature in the other. One can merely say that the two were contemporaneous
movements. Moreover, since Buddhist and Hindu tantra practitioners often frequented the
same sacred places, each group probably influenced the other.
Buddhologists and traditional Tantrayana scholars agree that the history of Buddhism
chronicles the adaptation of basic Buddhist themes to varying cultural milieus, but they differ
in their explanations of the process. Buddhologists do not accept that Buddha taught the
tantras. They posit that later masters developed a tantra form of Buddhism and composed its
texts to accord with the spirit of the times in India. Traditional Tantrayana scholars, on the
other hand, assert that Buddha's supramundane powers enabled him to foresee cultural
developments and that he personally taught tantra to suit people of the future. Thus, "when the
times were ripe," those who secretly transmitted the tantras - orally or buried in their mental
continuums - made them available to receptive practitioners. Alternatively, Buddha revealed
the tantras in pure visions to the highly accomplished masters who first recorded them. The
explication of each scholarly group accords with its particular view of Buddha and the general
Buddhist principle of teaching with skillful means.
