अपाने जुह्वति प्राणं प्राणेऽपानं तथापरे | प्राणापानगती रुद्ध्वा प्राणायामपरायणाः
apāne juhvati prāṇaṃ prāṇe.apānaṃ tathāpare . prāṇāpānagatī ruddhvā prāṇāyāmaparāyaṇāḥ
一些人通过抑制出息和入息的流动，持续练习生命能量的控制（普拉那亚玛），将出息献祭于入息之中；而另一些人则将入息献祭于出息之中。
Constantly practising control of the vital forces by stopping the movements of the outgoing and the incoming breaths, some offer as a sacrifice the outgoing breath in the incoming breath; while still others, the incoming breath in the outgoing breath.
一些瑜伽士练习吸气（Puraka），一些练习呼气（Rechaka），还有一些练习屏息（Kumbhaka）。通过普拉那亚玛（Prāṇāyāma）的练习，五种次级普拉那和其他普拉那融入主普拉那（MukhyaPrana）。当普拉那被控制时，心念也停止游荡，变得稳定；感官也被削弱并融入普拉那。正是通过普拉那的振动，心智和感官的活动得以维持。如果普拉那被控制，心智、智力和感官便停止运作。
Some Yogis practise Puraka (inhalation)? some Yogis practise Rechaka (exhalation)?,and some Yogis practise Kumbhaka (retention of breath).The five subPranas and the other Pranas are merged in the chief Prana (MukhyaPrana) by the practice of Pranayama. When the Prana is controlled? the mind also stops its wanderings and becomes steady the senses are also thinned out and merged in the Prana. It is through the vibration of Prana that the activities of the mind and the senses are kept up. If the Prana is controlled? the mind? the intellect and the senses cease to function.
