एकान्तरे त्वानुलोम्यादम्बष्ठोग्रौ यथा स्मृतौ । क्षत्तृवैदेहकौ तद्वत् प्रातिलोम्येऽपि जन्मनि ॥ १३ ॥

sanskrit

As an Ambashtha and an Ugra, (begotten) in the direct order on (women) one degree lower (than their husbands) are declared (to be), even so are a Kshattri and a Vaidehaka, though they were born in the inverse order of the castes (from mothers one degree higher than the fathers).
