QA : Verse no. 4.29

Question 1 : How the process of K???a consciousness is superior to other yogic processes mentioned in this verse for advancement in spiritual realization ?

Answer 1 : "The prā?āyāma yogī practices breathing the opposite way until the currents are neutralized into pūraka, equilibrium. Similarly, when the exhaled breathing is offered to inhaled breathing, it is called recaka. When both air currents are completely stopped, it is called kumbhaka-yoga. By practice of kumbhaka-yoga, the yogīs increase the duration of life by many, many years. A K???a 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 K???a, have no chance of becoming otherwise engaged. So at the end of life, he is naturally transferred to the transcendental plane of Lord K???a; consequently he makes no attempt to increase his longevity. He is at once raised to the platform of liberation. A K???a 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 K???a prasādam, or food which is offered first to the Lord."
