Matsya Purana — The Attendant Hosts of the Sun and Moon: Monthly Gaṇas
पिबन्ति द्विकलं कालं शिष्टास्तास्तु कलास्तु याः विनिःसृष्टं त्वमावास्यां गभस्तिभ्यस्तदामृतम् //
pibanti dvikalaṃ kālaṃ śiṣṭāstāstu kalāstu yāḥ viniḥsṛṣṭaṃ tvamāvāsyāṃ gabhastibhyastadāmṛtam //
For a period of two kalās they drink; and those remaining kalās—preserved according to rule—drink that amṛta, the nectar which, on the night of Amāvāsyā, is released from the rays of the Sun.
It presents a cosmological “time-and-essence” teaching: amṛta is described as being released at amāvāsyā and “drunk” according to measured units (kalā), reflecting how subtle essences are regulated by cosmic time even across dissolution-oriented themes.
By emphasizing precise sacred timing (kalā, amāvāsyā), it supports dhārmic discipline: rulers and householders are expected to align vows, offerings, and observances with correct lunar timings rather than acting arbitrarily.
Ritually, it highlights amāvāsyā as a potent time connected with subtle “nectar/essence”; such timing is often used for śrāddha, vrata, and purification observances—useful context when applying Matsya Purana ritual calendars alongside temple/rite scheduling.
