According to Patanjali’s Yoga Sutras, ‘Jalandhara bandha, uddiyana bandha and mula bandha are situated in the throat, abdomen and perineum respectively. With the performance of these three bandhas the rechaka (exhalation) and pooraka (inhalation) ceases to function. With this the senses become purified and kevala (enlightenment) takes place.’ (YS 5,6,8) This combination of three bandhas that holds such promise is known as the maha bandha, from the Sanskrit word meaning ‘great’.
