Cyavana’s Water-Vow and the Ethics of Cohabitation (स्नेह-सम्वास-धर्मः)
वैश्यस्य वर्तमानस्य वैश्यायां भरतर्षभ । शूद्रायां चापि कौन्तेय तयोविनियम: स्मृत:
vaiśyasya vartamānasya vaiśyāyāṃ bharatarṣabha | śūdrāyāṃ cāpi kaunteya tayor viniyamaḥ smṛtaḥ ||
Bhīṣma dijo: «Oh toro entre los Bhāratas, oh hijo de Kuntī: cuando un vaiśya, viviendo en el estado de cabeza de familia, tiene hijos nacidos de una mujer vaiśyā y también de una mujer śūdrā, se recuerda que la regla para asignarles sus porciones es la misma que la regulación establecida para tales descendientes mixtos.»
भीष्म उवाच
The verse states that Smṛti tradition recognizes a specific, established rule (viniyama) for allocating wealth/entitlements when a Vaiśya has sons from both a Vaiśyā and a Śūdrā; Bhīṣma emphasizes that the distribution should follow the remembered legal-ethical regulation rather than personal preference.
In the Anuśāsana Parva, Bhīṣma instructs Yudhiṣṭhira on dharma and social-legal norms. Here he addresses a case of mixed parentage within a Vaiśya household and indicates that traditional law provides a defined rule for how the two sets of sons are to be treated in matters like division of property.
