Developing your praanic energy
Sit in easy pose sukasana with the spine straight. Interlace the fingers of both hands and rest then comfortably in your lap. Keep your eyes open – this is not a meditation. Purse your lips and push them out, make a straw through which you can suck air into the body. Continuously inhale through the mouth in powerful, rhythmic strokes (1 per second). Do Not take the time to exhale.
In fact completely forget about the exhalation. Inhale under your own automatic system, inhale and just keep on inhaling, we are trying to overload the praanas The exhalation will take care of itself, it will automatically leak out somewhere, do not concern yourself. It is just the mind that doubts, the body finds this very easy once the rhythmic inhalation is mastered. Very powerful bursts of air are sucked in through the mouth and create a rhythmic beat at the thoracic diaphragm. The inhalation is very similar to trying to suck a thick milkshake through a straw, or a duck drinking water through its bill.
This kriya will make you sweat and make you a little cold. It is a very youthful process as it brings deep relaxation to the mental body. Drink the air through the mouth. Do it with your full strength for 5 minutes maximum.
To finish: Inhale deeply and calmly hold the breath for 30 seconds. Exhale and relax.
Before doing this kriya the mind doubts that the body can continuously inhale for five minutes without a conscious exhalation. After doing the exercise, you will never be the same again. If undertaken in a very honorable manner it develops the praanic energy to multi-million cycles, it is not a joke, it is a very powerful exercise. It will change you completely, it changes the way you think as it takes away tension.
