What is PRANA?

Prana is something which each individual is born with. It is capable of being exercised and strengthened just as our limbs, intellect and mind can. During the exercising of prana, external air comes into play, but prana should not be identified or mistaken with the air we breathe. Prana is attached to the body, and so long as it is thus attached, man is alive. Yoga treatises say that this prana forms a sheath round our body extending for about twelve inches around it. The more gently we breath, we conserve it, the more violently we breath we waste it. The proper ways of exercising and conserving prana have been laid down by the ancient seers in the light of their rich experience.
