Bhagavad Gita 18.19

ज्ञानं कर्म च कर्ता च त्रिधैव गुणभेदतः।प्रोच्यते गुणसंख्याने यथावच्छृणु तान्यपि॥

jñānaṃ karma ca kartā ca tridhaiva guṇabhedataḥ |procyate guṇasaṃkhyāne yathāvacchṛṇu tānyapi ||

Knowledge, action, and actor are declared in the science of the Gunas (Sankhya philosophy) to be of three kinds only, according to the distinction of the Gunas. Of these, hear duly.

The knowledge, the action, and the doer differ according to their qualities. Listen to this as well.

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