ज्ञानं कर्म च कर्ता च त्रिधैव गुणभेदतः । प्रोच्यते गुणसंख्याने यथावच् छृणु तान्य् अपि ॥

jñānaṃ karma ca kartā ca tridhaiva guṇa-bhedataḥ | procyate guṇa-saṃkhyāne yathāvac chṛṇu tāny api ||

Knowledge, action, and agent are each three-fold by guṇa-distinction — as declared in the guṇa-science. Hear them.

Word by word (3)
jñānaṃ karma ca kartā ca tridhaiva guṇa-bhedataḥ
— knowledge (jñānam), action (karma), and agent (kartā) — all three are each only (eva) three-fold (tridhā) by the distinction of guṇas (guṇa-bhedataḥ = by the differentiation of guṇas)
procyate guṇa-saṃkhyāne yathāvac chṛṇu tāny api
— these are declared (procyate = stated) in the guṇa-enumeration (guṇa-saṃkhyāna = the Sāṃkhya-style counting/analysis of guṇas), accurately/as-they-are (yathāvat); hear (śṛṇu) them (tāni) also (api) — the announcement that the three-fold guṇa analysis of jñāna/karma/kartā follows
guṇa-saṃkhyāne
— in the enumeration/analysis of guṇas (guṇa = sattva/rajas/tamas; saṃkhyāna = numbering/counting/analyzing); the Sāṃkhya philosophical framework is being explicitly invoked — as in V13's sāṃkhye kṛtānte

Knowledge, action, and agent — all three are each three-fold in accordance with the distinction of guṇas, as declared in the science of guṇas. Hear them also duly.

A modern analogy

V19 is the table of contents for V20-28: 'I will now analyze each of knowledge, action, and agent through the three-guṇa lens.' Just as Ch.17 analyzed food/yajña/tapas/dāna through the three guṇas, Ch.18 now applies the same framework to the fundamental categories of knowing, acting, and agency.

V19 is the transition announcement from the five-cause analysis (V13-17) to the three-fold guṇa analysis of jñāna/karma/kartā (V20-28). This section represents one of the Gita's most philosophically comprehensive passages — a systematic Sāṃkhya-style analysis of the fundamental categories of mind and action. V20-22 will give three-fold jñāna; V23-25 three-fold karma; V26-28 three-fold kartā. The section culminates in V30-32's three-fold buddhi and V33-35's three-fold dhṛti (fortitude) before the chapter's famous concluding sections.

Guṇa-saṃkhyāne (in the Sāṃkhya enumeration of guṇas) explicitly marks this section as Sāṃkhya-philosophical in approach. The Gita is here integrating the Sāṃkhya analytical method (classifying reality through guṇa-categories) with Vedānta's metaphysics and Yoga's practical ethics. This integration is one of the Gita's distinctive contributions: it uses Sāṃkhya's analytical precision while transcending its dualist framework.
