Phala of Vrata, Niyama, Svādhyāya, Dama, Satya, Brahmacarya, and Service (व्रत-नियम-स्वाध्याय-दम-सत्य-ब्रह्मचर्य-शुश्रूषा-फलप्रश्नः)
तिलालाभे तु यो दद्याज्जलधेनुं यतव्रत: । स कामप्रवहां शीतां नदीमेतामुपाश्ुते
tilālābhe tu yo dadyāj jaladhenuṃ yatavrataḥ | sa kāmapravahāṃ śītāṃ nadīm etām upāśnute ||
若无芝麻，持戒守誓之人若施与“水牛”（以牛形象征之水施），便得亲近此清凉之河；此河能载来所愿之物，使其居其畔而享福，得施舍之吉果。

Educational Q&A
When a standard offering (here, sesame) is unavailable, one should still uphold dharma through an appropriate substitute gift—given with discipline and vow-observance. Such sincere charity bears a fitting reward, symbolized by access to a cool, wish-fulfilling river.
Nāciketa describes the merit (phala) of a specific charitable act: donating a jaladhenu. The verse presents this act as leading the donor to a pleasant, cool river that ‘brings’ desired enjoyments—an imagistic way of stating the auspicious results of dharmic giving.
