Translation:
"By the practicing Yogin should be drawn in the vital air through the Solar Nadi.
After performing Kumbhaka as prescribed in the rule, he should expel (it) through the lunar (Nadi).
This, which kills many a disease of the belly and extirpates the malignant influence due to (intestinal) worms, should often and often be performed and is known as Surya-bheda (breaking through the Solar Nadi). "
