[Commentary:] 81) One who performs Omkar Kriya with utterance - meaning performing pranayam from the door at the region of the anus to the eyebrows - he can see the Face in Kutastha.

Making vayu like a rope from the throat to the eyebrows - "kua" [well] - meaning throat, heart, navel, lingamula, Muladhar - all the lotuses that are there in these five elements - draw vayu through the roadway of this tube, bring it into the middle of the eyebrows - meaning: into the Ajna chakra and merge there.  vs.22

Pratyahar happens with 12 pranayams; dhyan with 1728 pranayams - the Stillness from the pulling and dropping of pranayam; dharana with 144 pranayams - "tarka" [enquiring and concluding] is in the Yoni - taking vayu in Tranquility to the middle of the eyebrows and discerning in the Lord in the head is called "tarka." "Samadhi" - 20,736 pranayams is called [leads to] "samadhi." This is what is called "sharanga yoga" [six-limbed yoga].

Via the lotus-stem-thread of the mouth, relinquish breath - meaning:  make is Still; in this way - via the sushumna path, it becomes Still like this spontaneously.  This is the indication of "kumbhak" - meaning: vayu moves in Stillness via the sushumna; that is the state of kumbhak

"Sreshtha uttamanga [the greatest and principal part of the body] (mouth)* brahmin" - when there is samadhi; the abode of all happiness is "swarga" [heaven]; when one performs Kriya, one is a "brahmin"; from that Mouth - Lord (Purushottama)."

[*and**Translator's note:  The parentheses and the text within them are in the original.]

The "mahadyuti" [Great Splendor] Kutastha is the secret Dharma of all dharma; He planned the different works of mouth, arms, thighs, feet and knees; brahmin - from the mouth; kshatriya - from the arms; vaishya - from the thighs; and shudra - from the legs/feet.

Purushottama manifests from the Mouth; by His wish there is "havya" and "kavya" [both are types of oblations] = the Divine Form is "kavya"-- Kutastha; all these merge into Brahman - meaning samadhi.

A brahmin eats all edibles by the Mouth - meaning: nothing at all remains except Brahman; He is beyond space - meaning Brahman -- when samadhi happens, everything including Kutastha is merged; what can be asked for other than this?
