Cyavana’s Water-Vow and the Ethics of Cohabitation (स्नेह-सम्वास-धर्मः)
समवर्णासु जातानां विशेषो<स्त्यपरो नृप । विवाहवैशिष्ट्यकृत: पूर्वपूर्वो विशिष्यते
samavarṇāsu jātānāṁ viśeṣo 'sty aparo nṛpa | vivāhavaśiṣṭyakṛtaḥ pūrvapūrvo viśiṣyate nareśvara ||
大王啊,即便是出自同一种姓之妇所生的诸子,其中亦有另一层差别须当留意。由于婚姻地位之殊别,诸子之间亦生等第:先婚所生之子为上,后婚所生之子为下,为幼。
भीष्म उवाच
Even when mothers are of the same varṇa, Bhishma states that the social-legal standing of sons can differ based on the precedence and recognized status of the marriages: the son of the earlier marriage is treated as senior/superior, and the son of a later marriage as junior.
In Bhishma’s instruction on dharma to the king, he is clarifying rules of familial and social precedence—how lineage ranking among sons is determined not only by varṇa but also by the order and distinct status of marriages.
