v1.c9.s2.86

Although we have maintained above that the alchemical Tantras had their origin about the 11th century A. D., it would be safer to conclude that the Tantric processes had sprung into existence long before this time, but that they did not acquire sufficient importance to force the attention of the physicians, as we have seen above that the R. V. and the A. V. existed almost side by side though the latter was held for a long time in contempt and was not quoted in the orthodox treatises.
