6.3

nirvṛtte pitṛmedhe tu dīpaṃ pracchādya pāṇinā | ācamya pāṇī prakṣālya jñātīñ cheṣeṇa bhojayet || tato jñātiṣu bhukteṣu svān bhṛtyān api bhojayet | paścāt svayaṃ ca patnī ca śrāddhaśeṣam udāharet

At a death or a birth, for female slaves, / and for wives taken in natural order of castes, / purification is equal to that of the master; when the master dies, it is by uterine kinship.

When the rite for the ancestors is over, covering the lamp with his hand, sipping water and washing his hands, he should feed his kinsmen with what remains; when they have eaten he should feed his own servants; afterwards he himself and his wife should eat the rest of the śrāddha.
