Bhagavad Gita 17.25

तदित्यनभिसन्धाय फलं यज्ञतपःक्रियाः।दानक्रियाश्च विविधाः क्रियन्ते मोक्षकाङ्क्षि॥

tadityanabhisandhāya phalaṃ yajñatapaḥkriyāḥ |dānakriyāśca vividhāḥ kriyante mokṣakāṅkṣi ||

Uttering "Tat," without aiming for the fruits, are the acts of sacrifice, austerity, and the various acts of gifts performed by those seeking liberation.

Those who desire deliverance begin their acts of sacrifice, austerity, or gift with the word "Tat" (meaning "That"), without thought of reward.

Our plain-language meaning of this verse is waiting for scholar review.
