Chapter 371 — Yama-Niyama and Praṇava-Upāsanā (Oṅkāra) as Brahma-vidyā
वाङ्मयः प्रणवः सर्वं तस्मात्प्रणवमभ्यसेत् अकारश् च तथोकारो मकारश्चार्धमात्रया
vāṅmayaḥ praṇavaḥ sarvaṃ tasmātpraṇavamabhyaset akāraś ca tathokāro makāraścārdhamātrayā
Pranava (Oṃ) là toàn thể của ngôn âm được phát ra; vì thế, người ta nên tu tập (tụng niệm và quán chiếu) Pranava—gồm các âm vị A, U, M, cùng với nửa mātrā (dư âm vi tế kết thúc).

Vidya Category: {"primary_vidya":"Mantra","secondary_vidya":"Vyakarana","practical_application":"Practice Oṃ-japa with correct phonemic segmentation (A-U-M) and awareness of the ardha-matra (anusvara/nada resonance) for meditative and ritual efficacy.","sutra_style":true}
Encyclopedic Reference: {"reference_type":"Definition","entry_title":"Pranava as Vangmaya; A-U-M with Ardha-matra","lookup_keywords":["pranava","vangmaya","a-u-m","ardha-matra","om-japa"],"quick_summary":"Oṃ is identified with the totality of articulated speech. Its correct practice is defined through its phonemic constituents A, U, M and the subtle half-matra resonance that completes the sound."}
Concept: Sound (vak) culminates in pranava; correct articulation leads to contemplative absorption.
Application: In japa: elongate A→U→M smoothly, then rest in the fading resonance (ardha-matra) with attention at the heart or between eyebrows, per one’s tradition.
Khanda Section: Mantra-shastra (Pranava/Om-upasana; Vedic phonetics and sacred syllable doctrine)

FAQs
It teaches Praṇava-upāsanā: disciplined repetition and contemplation of Oṃ as composed of A, U, M plus the subtle ardha-mātrā (the concluding resonance/nāda).
It preserves a compact, technical doctrine of sacred phonetics and mantra-theory (śabda-tattva), showing the Agni Purāṇa’s coverage beyond mythology into practical spiritual disciplines and linguistic/ritual science.
By grounding practice in the Praṇava as the essence of all speech, it frames Oṃ-japa and contemplation as a direct purifier of mind and a unifying support for meditation leading toward spiritual realization.
