Asana

Yoga asana or postures are systematic exercises carried out for the purpose of keeping the mind and body fit for spiritual purposes. Asana are not just physical exercises as generally understood; no doubt the asana help in nourishing the entire body and all the body systems, but the purpose of asana is entirely different. Sitting in a steady and comfortable posture and keeping the mind from running outwards requires the body to be in an excellent condition. The flow of blood should be normal and there should be no blockage anywhere in the body. Also once the divine currents start getting activated during meditation a weak body cannot sustain them, a feeble body and mind may not be able to reach the state of super consciousness.
