The true breathing is not merely the inspiration and expiration from the lungs which is merely the mechanism of it, but a drawing in of the universal energy of Prana into every cell of the body.<ref>http://incarnateword.in/cwsa/29/sankhya-and-yoga#p21</ref>

... In simpler words, Pranayama is the control of the breath or vital power; for breathing is the chief physical functioning of the vital forces. <ref>http://incarnateword.in/cwsa/23/the-systems-of-yoga#p10</ref>

...Pranayama achieves that through two ways. First, it completes the perfection of the body. The vitality is liberated from many of the ordinary necessities of physical Nature; robust health, prolonged youth, often an extraordinary longevity are attained. On the other hand, Pranayama awakens the coiled-up serpent of the Pranic dynamism in the vital sheath and opens to the Yogin fields of consciousness, ranges of experience, abnormal faculties denied to the ordinary human life while it puissantly intensifies such normal powers and faculties as he already possesses.<ref>http://incarnateword.in/cwsa/23/the-systems-of-yoga#p10</ref>

Pranayama..is done by various regulations of the breathing, starting from equality of respiration and inspiration and extending to the most diverse rhythmic regulations of both with an interval of inholding of the breath. In the end the keeping in of the breath, which has first to be done with some effort, and even its cessation become as easy and seem as natural as the constant taking in and throwing out which is its normal action. <ref>http://incarnateword.in/cwsa/23/hathayoga#p10</ref>

But instead of doing equal amounts of time, it might be better to do less for inhaling and more for holding the breath. The holding part is extremely interesting! When the air is inside, let's say you have a headache or a sore throat or a pain in your arm, anything—then you take the air….and direct it to the unwell part... very, very helpful and pleasant and interesting. You see the force go to the spot, settle in and stay there, all sorts of things.<ref>http://incarnateword.in/agenda/03/february-24-1962#p58</ref>
