The same routine of worship should be observed each month, on the twelvth day of the bright fortnight, and continued on for a whole year. The worshipper should observe a fast on the 13th day of the bright fortnight and worship Viṣṇu. On the 12th day of every bright fortnight, he should live only on fruits and sleep on the floor. At the beginning of the 13th month, he is to finally complete his cycle of fasts by performing worship as mentioned before, and on its completion he should worship the golden image of Cupid. Afterwards, white sesamum, mixed with clarified butter, should be poured into fire and at the time of each sacrificial offering the various names of Cupid, already mentioned, prefixed with om and suffixed with Svâhâ, should be pronounced. At the close of the sacrifice, the worshipper should also worship the officiating priest and his consort, and then dismiss all his Brâhmaṇa guests after feasting, garlanding, and giving them presents of clarified butter, cows, decently-arranged beds, clothes, ornaments, sugarcane. The golden image of Cupid should be given to the officiating priest along with other presents mentioned above, according to the means of the worshipper.—21-26.
