Word by word (3)
karmaṇaḥ su-kṛtasya sāttvikaṃ nirmalam phalam āhuḥ
— the fruit of righteous/good action (su-kṛta = well-done) is said (āhuḥ = they say, tradition declares) to be sattvic and pure (sāttvikaṃ nirmalam)
rajasas tu phalam duḥkham
— the fruit of rajasic (karma) is pain (duḥkha) — the inevitable result of desire-driven action
ajñānaṃ tamasaḥ phalam
— ignorance (ajñāna) is the fruit of tamasic karma — the accumulation of tamas deepens nescience

The fruit of righteous (sattvic) action is said to be pure and auspicious. The fruit of rajasic action is pain. The fruit of tamasic action is ignorance. Each guṇa produces a corresponding karmic result.

A modern analogy

Plant sattva seeds → harvest clarity and peace. Plant rajas seeds → harvest restlessness and eventual pain (even when the desire is fulfilled, more desire follows). Plant tamas seeds → harvest fog and confusion — you don't even know you're in darkness. Each seed grows true to its nature.

V16 gives the KARMIC FRUITS of each guṇa — connecting the psychological states (V6-V13) and rebirth patterns (V14-V15) to the moral-karmic order. The fruits are: sattva → nirmala (pure/auspicious); rajas → duḥkha (pain); tamas → ajñāna (ignorance). This is the karma-theology of the guṇas: your guṇic orientation determines both the quality of your experience and the direction of your karmic accumulation.

The saying 'āhuḥ' (they say) invokes the Vedic and smṛti tradition's consensus on karmic fruits. The symmetry is profound: sattva produces its characteristic quality outward (nirmala/pure action), rajas produces its characteristic quality inward (duḥkha/pain — rajas was pain-producing from V5 onwards), tamas produces its essential root (ajñāna — tamas IS born of ajñāna per V8, so its fruit is more ajñāna, a feedback loop).
