Chapter 4 · Verse 29
Jnana Yoga
ज्ञानयोग
In plain words
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.
Translation
4.29 Others, with restricted diet, are devoted to the control of breath. Some sacrifice the inward breath in the outward breath. Similarly others sacrifice the outward breath in the inward breath. Some others, stopping the flow of both the inward breath and the outward, sacrifice the inward breaths and outward breaths.
Meaning
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.
