High Quality Content by WIKIPEDIA articles! Tummo is a practice associated with the subtle body of energy-channels, energy-winds and energy-drops. The practices are taught in a suite of advanced sadhana, the Six Yogas of Naropa, which describe contemplative practices, spiritual energetic work or meditations such as those used in the Himalayan traditions of Vajrayana and Bön. This discipline is key to all advanced (completion stage) spiritual practices in Tibetan Buddhism. Himalayan disciplines such as Yantra Yoga, where yantra is the synonym for asana, also work with this "inner heat". Tummo-meditation is commonly associated with descriptions of intense sensations of body heat, which are a partial effect, rather than a goal, of the practice. Stories and eyewitness accounts abound of yogi practitioners being able to generate sufficient heat to dry wet sheets draped around their naked bodies while sitting outside in the freezing cold, not just once, but multiple times.
