सपिण्डता तु पुरुषे सप्तमे विनिवर्तते । समानोदकभावस्तु जन्मनाम्नोरवेदने ॥ ६० ॥
sanskrit
But the Sapinda-relationship ceases with the seventh person (in the ascending and descending lines), the Samanodaka-relationship when the (common) origin and the (existence of a common family)-name are no (longer) known.
