।।4.29 4.30।।दूसरे कितने ही प्राणायामके परायण हुए योगीलोग अपानमें प्राणका पूरक करके प्राण और अपानकी गति रोककर फिर प्राणमें अपानका हवन करते हैं तथा अन्य कितने ही नियमित आहार करनेवाले प्राणोंका प्राणोंमें हवन किया करते हैं। ये सभी साधक यज्ञोंद्वारा पापोंका नाश करनेवाले और यज्ञोंको जाननेवाले हैं।
4.29 Pranayama-parayanah, constantly practising control of the vital forces-i.e. they practise a form of pranayama called Kumbhaka (stopping the breath either inside or outside) [Three sorts of motion of Pranayama (control of the vital forces) are, one by which we draw the breath in, another by which we throw it out, and the third action is when the breath is held in the lungs or stopped from entering the lungs.-C.W., Vol.I, 1962, p. 267. Thus, there are two kinds of Kumbhaka-internal and external.]-; prana-apana-gati ruddhva, by stopping the movements of the outgoing and the incoming breaths-the outgoing of breath (exhalation) through the mouth and the nostrils is the movement of the Prana; as opposed to that, the movement of Apana is the going down (of breath) (inhalation); these constitute the prana-apana-gati, movements of Prana and Apana; by stopping these; some juhvati, offer as a sacrifice; pranam, the outgoing breath, which is the function of Prana; apane, in the incoming breath, which is the function of Apana-i.e. they practised a form of pranayama called Puraka (filling in); while tatha apare, still others; offer apanam, the incoming breath; prane, in the outgoing breath, i.e. they practise a form of pranayama called Recaka (emptying out). [Constantly practising control of the vital, forces, they perform Kumbhaka after Recaka and Puraka.]
4.29 See Comment under 4.30
4.29 - 4.30 Other Karma Yogins are devoted to the practice of breath control. They are of three types because of the differences in inhalation, exhalation and stoppage of breath. Puraka (inhalation) is that in which the inward breath is sacrificed in the outward breath. Recaka (exhalation) is that when the outward breath is sacrificed in the inward breath. Kumbhaka (stoppage of breath) is that when the flow of both inward and outward breaths is stopped. The clause, restricting of diet, applies to all the three types of persons devoted to the control of breath. All these, according to their liking and capacity are engaged in performing the various kinds of Karma Yoga beginning from the sacrifice of material objects to the control of breath. They know and are devoted to sacrifices comprising obligatory and occasional rituals preceded by the performance of the great sacrifices (Panca-Maha-Yajna), as alluded to in Creating men along with the sacrifices (3.10). Because of this only, their sins are done away with. Those who are engaged in Karma Yoga by sustaining their bodies only by the ambrosia of sacrificial remains will go to the eternal Brahman. Go to Brahman here means realise the self which has Brahman for Its soul.
