Lord Kurma (Vishnu) instructing Indradyumna / sages on yogic nyasa and deity-propitiation through the sense-organs
Primary Rasa: shanta
Secondary Rasa: adbhuta
It implies that inner worship is performed through the body’s gateways (nostrils, ears), pointing to an indwelling sacred presence where external deities are contemplated as powers within the practitioner—an approach consistent with Purāṇic yoga that leads attention inward toward the Self.
This is an indriya-nyāsa style practice: touching specific sense-organs while invoking corresponding deities (here, the Nāsatyas at the nostrils and Vāyu–Agni at the ears) to purify perception and steady prāṇa, supporting meditation and mantra-sādhana.
Though the named deities are Vedic (Aśvins, Vāyu, Agni), the method reflects a broader Kurma Purana synthesis: Vishnu (as Kurma) teaches a yogic ritual technology also valued in Śaiva/Pāśupata milieus, presenting devotional-yogic practice as shared and harmonious rather than sectarian.
