After thus taking his meals in the night, the devotee, on the Punarvasu asterism day, should put some rice, along with some ghee, in a vessel made of fig-leaves. And should then give it away to the Brâhmaṇa, after putting some gold in it. Then, on the seventh day of the fast, he should give to the Brâhmaṇa a couple of raiments.—18-19.
