FAQs
Dedicating tīrtha-acts for others affects one’s own share of merit, with special emphasis on the heightened value of serving one’s parents.
No single tīrtha is named; the teaching applies to tīrtha-snāna generally within the Revā Khaṇḍa.
A phala rule: bathing for listed relatives yields the doer 1/8 merit; doing it directly for parents yields 1/4 merit.
