व्याख्या / Traditional Commentary & Notes
Classical Exegesis
Prāṇāyāma comprises the modifications (vṛttiḥ) of breath—external exhalation (bāhya), internal inhalation (abhyantara), and cessation (stambha)—which are measured (paridṛṣṭaḥ) by location (deśa), duration (kāla), and count (saṅkhyā), resulting in a breath that is prolonged (dīrgha) and subtle (sūkṣma)
