Nirūpaṇa (Nāḍī–Svara-Nirūpaṇam): Breath Currents, Omens, and Action-Timing
निर्गमे तु भवेद्वामा प्रवेशे दक्षैणा स्मृता / इडाचारे तथा सौम्यं चन्द्रसूर्यगतस्तथा
nirgame tu bhavedvāmā praveśe dakṣaiṇā smṛtā / iḍācāre tathā saumyaṃ candrasūryagatastathā
Khi thở ra, dòng bên trái được xem là đang vận hành; khi hít vào, dòng bên phải được ghi nhận là đang vận hành. Khi kênh Iḍā hoạt động thì hiền hòa, mát dịu, tương ứng với lộ trình của Mặt Trăng và Mặt Trời theo thứ tự.
Lord Vishnu (in dialogue with Garuda/Vinata-putra)
Dosha: Pitta
Concept: Outgoing breath relates to left current; incoming to right; iḍā is gentle/cooling and corresponds to lunar course, while the counterpart aligns with solar course.
Vedantic Theme: Order (ṛta) reflected in the body; knowledge of prāṇa as a means to self-regulation and clarity of mind.
Application: Track nostril dominance during daily activities; use lunar (iḍā) periods for calming, study, prayer; use solar periods for exertion and outward tasks, aiming for balance.
Primary Rasa: shanta
Secondary Rasa: adbhuta
Type: subtle-body (nostrils; iḍā/piṅgalā; prāṇa movement)
Related Themes: Garuda Purana 1.67.10-11 (qualities of currents; danger of combined flow); Garuda Purana 1.67.13-14 (task-specific efficacy)
This verse treats iḍā as a cooling, gentle current aligned with the lunar principle, used as an indicator for the quality and auspiciousness of actions.
It links left/right functioning (commonly read as nostril or nāḍī dominance) with outward vs inward movement and with lunar/solar correspondences, implying that bodily currents reflect subtle energetic states.
Observe whether the left or right flow feels dominant before beginning or entering an activity, using it as a mindfulness cue to act calmly (lunar/left) or decisively (solar/right) rather than impulsively.
