When aparāhṇa has passed, that portion of time is called sāyāhna, the evening twilight. A day consists of fifteen muhūrtas, and evening comprises only three muhūrtas.
Sage Parāśara (teaching Maitreya)
Concept: Evening (sāyāhna) begins after aparāhṇa, and the full day is reckoned as fifteen muhūrtas, with sāyāhna comprising three.
Vedantic Theme: Dharma
Application: Use evening as a deliberate transition—review actions, practice sandhyā/namajapa, and reset intention for the next day.
Vishishtadvaita: Daily rhythm supports continual remembrance (smaraṇa) of the Lord across changing temporal states.
This verse defines sāyāhna precisely as the period after aparāhṇa, establishing an authoritative time-division that supports dharma-oriented daily order.
He measures the day in muhūrtas, stating that the full day is fifteen muhūrtas and specifying the evening as a fixed subset of three.
Even without naming Vishnu directly, the teaching reflects the Purana’s view that kāla (ordered time) is part of the cosmic governance ultimately rooted in the Supreme Reality—Vishnu.
