This system of yoga for controlling the breathing process is called pranayama, and in the beginning it is practiced in the hatha-yoga system through different sitting postures. All of these processes are recommended for controlling the senses and for advancement in spiritual realization. This practice involves controlling the airs within the body so as to reverse the directions of their passage. The apana air goes downward, and the prana air goes up. The pranayama-yogi practices breathing the opposite way until the currents are neutralized into puraka. equilibrium. Offering the exhaled breath into the inhaled breath is called recaka. When both air currents are completely stopped, one is said to be in kumbhaka-yoga. By practice of kumbhaka-yoga. one can increase the duration of life for perfection in spiritual realization. The intelligent yogi is interested in attaining perfection in one life, without waiting for the next. For by practicing kumbhaka-yoga. the yogis increase the duration of life by many, many years. A Krishna conscious person, however, being always situated in the transcendental loving service of the Lord, automatically becomes the controller of the senses. His senses, being always engaged in the service of Krishna, have no chance of becoming otherwise engaged. So at the end of life, he is naturally transferred to the transcendental plane of Lord Krishna; consequently he makes no attempt to increase his longevity. He is at once raised to the platform of liberation, as stated in Bhagavad-gita (14.26):
mam ca yo 'vyabhicarena
"One who engages in unalloyed devotional service to the Lord transcends the modes of material nature and is immediately elevated to the spiritual platform." A Krishna conscious person begins from the transcendental stage, and he is constantly in that consciousness. Therefore, there is no falling down, and ultimately he enters into the abode of the Lord without delay. The practice of reduced eating is automatically done when one eats only krishna-prasadam, or food which is offered first to the Lord. Reducing the eating process is very helpful in the matter of sense control. And without sense control there is no possibility of getting out of the material entanglement.
