Among all the systems of physical exercises, Hatha Yoga practiced and prescribed by the ancient Rishis and sages stands unrivalled and unique. It is the perfect system. Brain, muscles, nerves, organs, tissues are toned and energized. All chronic disease is rooted out. It deals with Shat Karmas, Asanas, Pranayama, Mudras, Bandhas, and exercises on concentration and mediation.
Asanas pertain to the physical body. They render the body firm and steady and eradicate physical ailments. Bandhas pertains to the Prana. They bind and unite the Prana and the Apana and send the united Prana-Apana along the Sushumna Nadi. Mudras concern the mind. They represent seals. They seal the mind with the soul or the Atman. They do not allow the mind to wander outside towards objects. They direct the externalizing mind towards the Atman in the chambers of the heart and fix it there. A combination of all these exercises is needed to have the maximum results.
