Heat Meditation

From g Tum-mo heat meditation:
"Monks in Tibet-that mountainous country so blessed with oddities-can consciously raise the temperature in their hands and feet 6-7º C (10-12º F), in laboratory conditions (Benson, et al., 1982). There appear to be several methods of g Tum-mo meditation, as described by Alexandra David-Neel (1965), but all seem to involve the visualization of oneself filled with fire. Whether, for adepts, such visualization is necessary for control of body temperature is not clear to me, because Benson reports that one of his research participants began undergoing g-Tummo changes every time he sat down. Monks will even have little contests where they spend a night on a river bank, repeatedly draping themselves with wet sheets, and seeing who can dry the most. I get cold just thinking about it.

It presumably takes some time to develop this ability, but apparently not so much that it is rare in Tibet: David-Neel claims that most Tibetans have the knowledge of how to do it, and that they put it to practical use.

What interests me about this is not simply that the mind has considerable control over the body-that is a familiar refrain from many areas of research. What interests me is that we could have this ability and not know it unless someone teaches us. No one had to teach me how to shiver, or to raise little body hairs, or to contract my blood vessels. So, if we are capable of mentally warming our extremities, why should we not automatically know how to do it? It seems that boundary in the temperature regulation system between what is automatic and what is susceptible to willed intervention is strangely situated."
