பிராணன் என்பது உடலுள் இயங்கும் வாயு; ‘ஆயாமம்’ என்பது அதன் கட்டுப்பாடு மற்றும் ஒழுங்குபடுத்தல். ஒரு மூச்சால் அளக்கப்படும் அளவே ‘பிராணாயாமம்’ என உரைக்கப்படுகிறது.
Skanda (deduced: Kāśīkhaṇḍa commonly Skanda → Agastya)
Tirtha: Kāśī
Type: kshetra
Listener: Śaunaka and ṛṣis (frame)
Scene: A teacher-sage explaining prāṇāyāma to a seated disciple: diagram-like depiction of breath cycle as a single mātrā; subtle wind (vāyu) motifs within the body; calm instructional setting in Kāśī.
Prāṇāyāma is disciplined regulation of the life-wind; spiritual progress begins with measured, conscious breath.
Kāśī is the broader sacred context of the chapter, presenting yogic discipline as a dharmic path within the city’s māhātmya.
It gives a definition and measure: prāṇāyāma is the restraint of prāṇa, counted in units of a single breath.
