अहोरात्रस्य यः सन्धिः सा सन्ध्या भवतीति ह / द्विनाडिका भवेत्सन्ध्या यावद्भवति दर्शनम्
ahorātrasya yaḥ sandhiḥ sā sandhyā bhavatīti ha / dvināḍikā bhavetsandhyā yāvadbhavati darśanam
موضع التقاء النهار والليل يُسمّى حقًّا «السَّندْهيا». وتمتد السَّندْهيا مقدار نادِكَاين، ما دام يبقى شيء من الرؤية (لدلالة حضور الشمس).
Lord Vishnu (in dialogue teaching Garuda/Vinata-putra)
Concept: Dharma requires correct kāla (timing); Sandhyā is a measurable ritual interval.
Vedantic Theme: Kāla as a governing principle of karma; right action aligned with time supports inner purity (antaḥkaraṇa-śuddhi).
Application: Observe Sandhyā within the defined window (approx. two nāḍikās); plan daily schedule around sunrise/sunset visibility rather than convenience.
Primary Rasa: shanta
Secondary Rasa: adbhuta
Type: temporal-liminal

This verse defines sandhyā as the sacred transition between day and night and fixes its ritual window, supporting disciplined daily worship as a dharmic practice.
Sandhyā is stated to be two nāḍikās, i.e., a traditional two-unit time window around the day–night junction, lasting as long as visibility remains.
Treat sunrise/sunset as disciplined prayer windows: keep a consistent routine for meditation, japa, or sandhyā-vandana near the day–night transition rather than delaying it arbitrarily.
