Rajasic knowledge represents partial understanding that sees only separation without underlying unity. While functional on a practical level, this perspective misses the deeper connections between beings, leading to action motivated by self-interest rather than universal welfare.

Tamasic knowledge represents the most limited perspective—focusing narrowly on isolated phenomena without understanding broader contexts or deeper principles. This constricted view leads to dogmatic thinking and actions that create harm due to ignorance of consequences.

Sattvic action embodies the ideal of nishkama karma (desireless action) taught throughout the Gita. By defining it as action performed without attachment yet with full dedication, Krishna presents the practical solution to Arjuna's dilemma about how to act in the world.

Tamasic action represents the most harmful category—actions undertaken without consideration of consequences, harm to others, or personal capacity. By highlighting how delusion leads to destructive behavior, Krishna completes his analysis of the quality of actions.

The sattvic doer represents the ideal agent who acts from wisdom rather than ego. This equanimity toward success and failure enables consistent performance of duty without the emotional turbulence that typically accompanies action, exemplifying the "skill in action" Krishna advocates.

The rajasic doer portrays common human motivation—passionate pursuit of results, emotional reactivity, and self-interest. This creates an endless cycle of elation and disappointment, as the actor remains emotionally entangled with outcomes beyond their control.
