tasmin sati śvāsa-praśvāsayor gati-vicchedaḥ prāṇāyāmaḥ

The line

That being in place, breath regulation is cutting the movement of inhalation and exhalation.

नेपालीमा

त्यो ठाउँमा बसेपछि प्राणायाम श्वास लिने र छोड्ने गतिको विच्छेद हो।

Where it sits

The fourth limb, defined. It does not begin from nowhere. tasmin sati (तस्मिन् सति) means the seat of 2.46 is already there. 2.50 will divide the cutting into external, internal, and suspended, and into place, time, and count.

Split: tasmin (तस्मिन्) + sati (सति) + śvāsa (श्वास) + praśvāsayoḥ (प्रश्वासयोः) + gati (गति) + vicchedaḥ (विच्छेदः) + prāṇāyāmaḥ (प्राणायामः)

The phrases

tasmin sati (तस्मिन् सति) is “that being in place,” the locative absolute you met as sati mūle (सति मूले). The posture is assumed. śvāsa-praśvāsayoḥ (श्वासप्रश्वासयोः) is genitive dual of the two breaths. gati-vicchedaḥ (गतिविच्छेदः) is the cutting of their movement. That cutting is prāṇāyāmaḥ (प्राणायामः).

Sanskrit in this line

Dual -yoḥ (योः) again, “of the two breaths.” tasmin (तस्मिन्) is the locative of tad (तद्), “in that,” a form to set beside tatra (तत्र) and tataḥ (ततः). sati (सति) with a locative is “while that is so.”

Say it back

Say what must already be in place, then what breath regulation is a cutting of.
