purakeṇa samāgatya svakīyaṃ hṛdyāntaraṃ śivāgninā punaḥ kṛtvā nāḍīsandhānamīdṛśaṃ
Étant parvenu à la stabilité par l’inhalation (pūraka) et, de nouveau, ayant embrasé la région intérieure de son propre cœur par le feu de Śiva (Śiva-agni), il doit opérer une telle jonction des nāḍīs (canaux subtils).

Alamkara Type: Rupaka
Concept: Prāṇa and consciousness are refined through breath and inner-agni; ‘nāḍī-sandhāna’ implies integration of dispersed energies into a coherent central flow.
Application: In meditation, use pūraka to settle attention, visualize a steady luminous fire in the heart, then guide awareness through a chosen channel sequence (e.g., iḍā–piṅgalā harmonization toward suṣumṇā).

FAQs
It teaches a pranayama-linked tantric visualization: using pūraka (inhalation) to stabilize attention in the heart-center and re-kindle the “Śiva-fire” (inner heat/tejas) to facilitate nāḍī-sandhāna—alignment or connection of subtle channels.
Beyond mythology, the Agni Purana preserves applied yogic physiology—prāṇāyāma terms (pūraka) and subtle-body mechanics (nāḍīs, heart-center, inner fire)—showing its coverage of practical spiritual technology alongside ritual, dharma, and other sciences.
By concentrating prāṇa in the heart and kindling inner fire in an auspicious (Śiva) mode, the practitioner is understood to purify and harmonize the nāḍīs, supporting steadiness of mind, deeper meditation, and inner purification (antaḥ-śuddhi).
