Maha bandha (Sanskrit: महा बंध, Mahā Bandha), translated as "The great bandha" is one of the internal locks or bandhas described and employed in yoga.
Practice
In a meditation pose for the duration of Bahir Kumbhaka all three bandhas are gradually assumed and held, in the following order: Jalandhara Bandha, Uddiyana Bandha and finally Mula Bandha. Releasing of the bandhas goes in the same order.[citation needed]
Precaution
All precaution from all three assumed bandhas should be considered.
