AMĀVĀSĪ . In Amarakośa we read about Amāvāsī: “Amāvāsyā tvamāvasyā darśaḥ sūryendusaṃgamaḥ”. Amāvāsī means New Moon. “Amā” means “Saha”. So Amāvāsī is the Union of Sun and Moon in the same rāśi. Once Bhṛgu Mahaṛsi cursed Agni. At that time Agni explained the importance of Amāvāsī. The oblations which are offered as homa into the fire become the food of the Devas and Pitṛs. Substances offered as homa on Purṇamāsī become food of the Devas and those offered on Amāvāsī become food of the Pitṛs. (M.B., Ādi Parva, Chapter 7).
