FAQs
Pilgrimage is paired with restraint and sharing; one should not consume at a tīrtha without setting aside a rightful portion.
Prabhāsa-tīrtha is the narrative setting, though the rule is framed as a general tīrtha practice.
After tīrtha-bathing (snāna), one should allocate half of one’s cooked-food share as a due offering/share (implying dāna/portioning).
