Revākhaṇḍa of the Skandapurāṇa manuscripts (RKS) 101.7

101.7

tatra tīrthe tu godānaṃ śaktimātreṇa dāpayet /
tad akṣayaṃ phalaṃ sarvaṃ jāyate pāṇḍunandana //

At that sacred bathing site, one should cause the gift of a cow to be given according to one's capacity alone; / all that fruit becomes imperishable, O son of Pāṇḍu.
