Tirtha: Svargadvāra (bounded stretch)
Type: ghat
Listener: Vipra/suvrata interlocutor
Scene: A schematic yet sacred cartography: Sarayū river with a marked starting point ‘Sahasradhārā’, an arrow pointing east, and a measured stretch indicated by dhanuṣ units; sages/pilgrims consult the measure on the riverbank.
Purāṇic dharma anchors holiness in real landscapes—mapping sacred merit onto rivers, directions, and measurable space.
Svargadvāra’s sacred extent is being described, situated along the Sarayū beginning from Sahasradhārā.
No explicit rite here; it provides geographic parameters for locating the tīrtha.
