तथैव व्यभिचारेण न वर्तन्ते परस्परम्
tathaiva vyabhicāreṇa na vartante parasparam
ભીષ્મે કહ્યું—એ જ રીતે તેઓ પરસ્પર પ્રત્યે વ્યભિચારથી વર્તતા નથી; પરસ્પર બંધનનો ભંગ કરતા નથી.
भीष्य उवाच
The verse upholds mutual fidelity as a dharmic norm: ethical relationships are sustained when neither party violates trust through vyabhicāra (infidelity or moral deviation).
In Bhīṣma’s instruction in the Śānti Parva, he is describing standards of proper conduct; here he emphasizes that people (especially spouses/partners, by context) should not act toward each other with betrayal, but maintain mutual loyalty.
