Jvara-Nidāna-Lakṣaṇa: Causes, Doṣic Types, Āma/Nirāma Stages, and Prognosis of Fever
अहोरात्रस्य सन्धौ स्यात्सकृदन्येद्युराश्रितः / तस्मिन्मांसवहा नाडी मेदोनाडी तृतीयके
ahorātrasya sandhau syātsakṛdanyedyurāśritaḥ / tasminmāṃsavahā nāḍī medonāḍī tṛtīyake
Pada pertemuan siang dan malam, ia berlaku sekali dan bersangkut dengan hari berikutnya. Pada pertemuan itu ada nāḍī yang membawa daging; dan pada bahagian ketiga ada nāḍī yang membawa lemak.
Lord Vishnu (in dialogue with Garuda/Vinata-putra)
Concept: Knowledge of subtle bodily timing and channels (nāḍī) as a basis for understanding periodic disorders.
Vedantic Theme: Deha as kṣetra (field) to be known; discriminative observation (viveka) applied to embodied processes without mistaking them for the Self.
Application: Use sandhi-times as diagnostic anchors for periodic symptoms; track patterns across day-boundaries and correlate with tissue/‘dhātu’ involvement (māṃsa, medas).
Primary Rasa: shanta
Related Themes: Garuda Purana 1.147 (context: nāḍī/doṣa periodicity and tissue involvement)
This verse treats the day–night junction as a technically significant transition point, associating it with specific nāḍīs (subtle channels) and bodily-tissue functions, indicating that time-junctions are linked to inner physiological/subtle processes.
Indirectly: by describing nāḍīs and transitional ‘sandhi’ points, it supports the Garuda Purana’s broader framework that the jīva’s experiences after death depend on subtle-body structures and timings, not only the gross body.
Treat dawn/dusk transitions as disciplined moments—calm the senses, maintain purity of diet and conduct—since the text frames sandhi-times as influential for subtle physiological processes.
