The Hevajra Tantra states also the alternative tradition of this highest bliss as third in order, thus implying its correspondence with the Heart Center of the Sacred Light of Vairoaana and his co-power, the Lord of the Center of the five Dhyani Buddhas. This tacit identification with the heart, and not the usually given hair-splitting reasons, is the true esoteric basis for the alternative order, which is thus seen not to be "artificial" as D. L. Snellgrove (Hevajra Tantra, Oxford, Vol. I, p. 137) surmises, saying hence not correctly that "it is associated with no improved interpretation of them (the Four Blisses) as a coherent set." This conclusion is understandable, however, for anyone not familiar with the relation of the Four Misses to the Chakras, for that relation provides the only solid and practical basis for the non-arbitrariness Snellgrove rightly sought. The moment the Chakras are taken into account, the only proper position for the Highest or Innate Bliss is seen at once to he third, placing it in direct correspondence with the Heart Center, where it uniquely belongs.--Ed.

^178:** Both from conversations with other practitioners of yoga and from personal experience, the editor can unequivocally state that the greatest heat (gTum-mo) can be generated and more easily controlled through the use of the Heart Center rather than through the navel plexus, allowing the latter to function unconsciously under orders of the Heart Center, as it were, and as a distribution point--but not bestowing any direct attention on the navel per se. Even on a cold night the bodily heat thus generated with comparative simplicity is pervasive and intense.--Ed.

^182:* There is a third and synthesizing view and doctrine here not mentioned in the text; namely, to maintain the conscious concentration of the prana at the heart center, letting that center be the means for the (unconscious) command to the Navel Center for its (the prana's) distribution.--Ed.
