somasya divase prāpte varṣaṃ yāvatkṛtakṣaṇaḥ ..
tasya pūjāṃ karotyevaṃ snāpayitvā vidhānataḥ ..
so'pi muktiṃ vrajenmartya etattātānmayā śrutam .. 34 ..

When the day of Soma arrives, one who seizes the opportunity for a year, / and thus performs its worship after bathing it according to the rule, / that mortal too goes to liberation: this was heard by me from my father.
