अपरे प्राणायाम परायणाः [apare prANAyAma parAyaNAH] Others who pursue the regulation of their breath नियताहाराः [niyatAhArAH] regulate the intake of food अपाने जुह्वति प्राणम् [apAne juhvati prANam] and give their breath as an offering in the process of exhalation. तथा [tathA] Yet others प्राणे अपानम् [prANe apAnam] offer their breath in the process of inhalation. अपरे [apare] Others प्राणापान गती रुद्ध्वा [prANApAna gatI ruddhvA] restrict the rate of inhalation and exhalation प्राणेषु प्राणान् जुह्वति [prANeSu prANAn juhvati] and offer the activities needed for sustenance of life to those activities themselves.

Others who practice [ karmayOga ] achieve excellence through the technique of breath control – प्राणायाम [prANAyAma] . These people are of three types: पूरक [pUraka] , रेचक [recaka] and कुम्भक [kumbhaka] .

People who give up the intake of breath in its outflow, as an offering are called पूरक [pUraka] . Those who give up the outflow in the intake are called रेचक [recaka] . Those who restrict the rate of intake and outflow of breath are called कुम्भक [kumbhaka] ; they leave life-sustaining activities in their breath itself.

All of them regulate their intake of food as well.
