Tirtha: Kāśī
Type: kshetra

FAQs
Even within socially discussed marriage forms, dharma distinguishes what uplifts from what degrades; the most sinful union is to be rejected as a mark of moral decline.
The broader setting is Kāśī (Vārāṇasī) in the Kāśīkhaṇḍa, where dharma is taught as part of Kāśī’s sacred instruction, though this verse itself is normative rather than site-descriptive.
No specific tirtha-ritual is prescribed here; it classifies marriage forms and condemns the most sinful type.
