Kundalini Yoga bandhas: Maha bandha
The Great Lock
The great lock is the application of all three locks simultaneously, with the breath held out. It is practiced after pranayama and exercise. It is done in various postures and combined with different mudras. It is part of the central infrastructure of Kundalini Yoga. Each student must master all the bandhas.
What the Great Lock achieves: 1. With all the locks applied, the body is in a perfect healing state. 2. The practice and perfection of this lock is said to cure many ailments: improper blood pressure, menstrual cramps, poor circulation, irregularity, wet dreams and excessive preoccupation with fantasy. The glands, nerves and chakras are rejuvenated.
