Bhagavad Gita 17.25

तदित्यनभिसन्धाय फलं यज्ञतपःक्रियाः।दानक्रियाश्च विविधाः क्रियन्ते मोक्षकाङ्क्षि ॥१७.२५॥

tadityanabhisandhāya phalaṃ yajñatapaḥkriyāḥdānakriyāśca 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.
