7.14.25

eṣu snānaṃ japo homo vrataṃ devadvijārcanam /
pitṛdevanṛbhūtebhyo yaddattaṃ taddhyanaśvaram //

25. On these days the performance of ablutions, *Japa*, *homa*, vows of austerity, worship of the gods and brahmins and whatever is offered to Pitris, the gods, wise men and Bhutas bears lasting good indeed (is productive of great benefit).
