rajanīṣu ca sarvāsu pibeddarbhodakaṃ budhaḥ
tatastu gītanṛtyādi kārayetsakalāṃ niśām //

The devotee should drink the water purified by the Kuśa grass, and carry on music and singing throughout the night; and, on the lapse of three quarters of the night thus past in vigil and prayer, the devotee should sleep in the last quarter, and then waking up, go and worship them, along with three couples of Brâhmaṇas and Brâhmaṇîs according to his means: if not three, at least, one couple should be worshipped. He should offer them sandal, flowers and cloths as well as bedsteads, with the mantra, “Namastu Jalaśâyine.” The night thus passed with watching, music and songs, the devotee, after bathing in the morning, should worship the Brâhmaṇa couples, as mentioned above. They should be fed according to his means, free from niggardliness. And then, after taking his meals, he should pass that day in listening to the Purâṇas.—19-23.
