Tummo

Tummo (Tibetan: gtum-mo; Sanskrit: caṇḍālī) literally means the fierce goddess of heat and passion in Tibetan Buddhist tradition. Tummo is found in the Mahasiddha Krishnacarya and the Hevajra Tantra texts.

Tummo (Tumo or Chandali yoga) also refers to a part of tantric meditation cycles and breathing exercises for yogic heat, that developed around the concept of fierce female deity. It is found in the Six Yogas of Naropa, Lamdre, Kalachakra and Anuyoga teachings of Tibetan Vajrayana. The purpose of tummo is to gain control over body processes during the completion stage of 'highest yoga tantra' (Anuttarayoga Tantra) or Anuyoga.

Tummo (gTum mo in Wylie transliteration, also spelled Tumo, or Tum-mo; Sanskrit caṇḍālī or Chandali) is a Tibetan word, literally meaning fierce [woman]. Tummo is a Tibetan word for inner fire.

Tummo may also be rendered in English approximating its phonemic enunciation as 'Dumo'.

The "center channel" (dbu ma or avadhuti) is the whole arterial system, or more specifically the aorta. The two "side channels" are the venous system (roma or rasanā) and the spinal column and nervous system (rkyang ma or lalanā). A chakra is any place in the body where there are clusters of arteries, veins and nerves.

In the practice of tummo, the visualization of lower ends to the three channels is primarily used to focus body awareness in the subnavel area.Breath retention, mulabandha and uddiyana bandha force vāyu (wind, air) and ojas into the arterial system. The heart rate slows, the karmic winds suspend and the venous blood returns less impurities into the blood stream. This leads to longevity. Ojas itself has two stores within the body—the heart and brain. Thus there is the visualization of blazing and dripping.
