According to some Tibetan authorities, the physical practice of sexual yoga is necessary at the highest level for the attainment of Buddhahood.
[11] The use of sexual yoga is highly regulated. It is only permitted after years of training.
[12] The physical practice of sexual yoga is extremely rare, and has been historically limited as well.
[13] A great majority of Tibetans believe that the only proper practice of tantric texts is metaphorically, not physically, in rituals and during meditative visualizations.
[14] The dominant
Gelug sect of Tibetan Buddhism holds that sexual yoga as an actual physical practice is the only way to attain Buddhahood in one lifetime. The founder of the sect
Tsongkhapa did not, according to tradition, engage in this practice, but instead attained complete enlightenment at the moment of death, that being according to this school the nearest possible without sexual yoga. The school also taught that they are only appropriate for the most elite practitioners, who had directly realized emptiness and who had unusually strong compassion. The next largest school in Tibet, the Nyingma, holds that this is not necessary to achieve Buddhahood in one lifetime.
[15] The current de facto
[16] leader of the Gelug sect, the fourteenth
Dalai Lama, holds that for ordained monks the practice should only be done as a visualization.
[17] Shingon, along with all non-tantric forms of Buddhism, does not recognize sexual yoga.
