यथा च प्राणादिः ॥ २० ॥
yathā ca prāṇādiḥ || 20 ||
yathā—As; ca—and; prāṇādiḥ—in the case of Pranas.
20. And as in the case of the different Pranas.
When the five different Pranas (vital forces) are controlled by Pranayama, they merge and exist as the chief Prana (which regulates respiration) merely maintaining life. From this we find that the effects, the various Pranas are not different from their cause, the chief Prana. So also with all effects; they are not different from their cause. Therefore it is established that the effect, the world, is identical with its cause, Brahman. Hence by knowing It everything is known.
