ഇഡാ വഴി പതുക്കെ പതിനാറു മാത്ര വരെ പൂരകം ചെയ്ത്, പിന്നെ നിറഞ്ഞ പ്രാണനെ അറുപത്തിനാലു മാത്ര വരെ കുംഭകത്തിൽ ധാരണം ചെയ്യണം. തുടർന്ന് പിംഗലാ നാഡി വഴി മുപ്പത്തിരണ്ടു മാത്രയിൽ രേചനം ചെയ്യണം; വീണ്ടും പിംഗലാ വഴി പൂരകം ചെയ്ത്, മുൻപുപോലെ സുസമാഹിതനായി ഇരിക്കണം. പ്രഭാതം, മധ്യാഹ്നം, സായാഹ്നം, അർദ്ധരാത്രി—ഈ നാലു സമയങ്ങളിലും—കുംഭകങ്ങൾ അഭ്യസിക്കണം; പതുക്കെ എൺപത് (ആവർത്തനം) വരെ, നാലു പ്രാവശ്യം അഭ്യാസം ചെയ്യണം. ഇങ്ങനെ മൂന്നു മാസം അഭ്യാസം ചെയ്താൽ നാഡീശുദ്ധി ഉണ്ടാകും; നാഡീശുദ്ധി സംഭവിക്കുമ്പോൾ അതിന്റെ ബാഹ്യലക്ഷണങ്ങളും പ്രത്യക്ഷമാകും.
[Same as Yogatattva.41] Having drawn the breath in through iḍā slowly for sixteen mātrās, he should retain the filled (breath) thereafter for sixty-four mātrās. He should exhale through the piṅgalā-nāḍī for thirty-two mātrās; again, having inhaled through piṅgalā, remaining well-collected as before. In the morning, at midday, in the evening, and at midnight, he should practice kumbhakas four times, gradually up to eighty (rounds). By practice for three months in this way, purification of the nāḍīs arises. And when nāḍī-purification occurs, then there are outward signs.
