Hanumān-mantra-kathana: Mantra-bheda, Nyāsa, Yantra, and Prayoga
आद्यवर्णैः पूरकं स्यात्पञ्चवर्गैश्च कुम्भकम् । रेचकं च पुनर्याद्यैरेवं प्राणान्नियन्य च ॥ १५३ ॥
ādyavarṇaiḥ pūrakaṃ syātpañcavargaiśca kumbhakam | recakaṃ ca punaryādyairevaṃ prāṇānniyanya ca || 153 ||
L’inspiration (pūraka) doit être accomplie avec les lettres initiales; la rétention (kumbhaka) avec les cinq groupes de lettres; et l’expiration (recaka) de nouveau avec les lettres initiales—ainsi l’on règle et l’on maîtrise les souffles vitaux (prāṇa).
Sanatkumara (teaching Narada)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It links prāṇāyāma to sacred sound (varṇa), teaching that breath regulation becomes more focused and purifying when coordinated with mantra/phonetic structure.
By disciplining prāṇa through mantra-like letter sequences, the mind becomes steady and fit for sustained remembrance and worship, which supports bhakti as concentrated attention on the divine.
Śikṣā (Vedic phonetics): it uses the organization of Sanskrit letters (initial sounds and the five vargas) as a technical method to time pūraka–kumbhaka–recaka in practice.
