kāmadhenupayaḥ pātre kṛtvā maghavatā svayam |
pānārthaṃ preṣitaṃ tasyāḥ pītaṃ caivāmṛtaṃ yathā ||

Indra himself, the king of the Devas, sends the nectar and the Heavenly Cow’s Milk in a pot to Her daily; and She subsists on that, alone.
O Lord! On drinking the Heavenly Cow’s Milk, the lotus eyed Sîtâ Devî is living without any hunger or thirst! I use to see Her daily.
