Bhagavad Gita 18.13

पञ्चैतानि महाबाहो कारणानि निबोध मे।सांख्ये कृतान्ते प्रोक्तानि सिद्धये सर्वकर्मणाम् ॥१८.१३॥

pañcaitāni mahābāho kāraṇāni nibodha mesāṃkhye kṛtānte proktāni siddhaye sarvakarmaṇām

Learn from Me, O mighty-armed Arjuna, these five causes, as declared in the Sankhya system, for the accomplishment of all actions.
