Krishna stresses purity in action. Yogis act without attachment, motivated by self-discipline rather than desire, and thus avoid bondage. This sets the foundation for Arjuna to see duty as a means of inner purification rather than material gain.

Krishna contrasts the peace attained by selfless action with the entanglement caused by desire-driven acts. By encouraging detachment, he reveals how the mind’s liberation depends more on intent than on the nature of action itself.

The "city of nine gates" metaphor represents the body, with the detached self residing within as an observer. This analogy encourages Arjuna to view himself as distinct from his physical actions, laying groundwork for liberation through detachment.

Ignorance obscures self-knowledge, Krishna notes, causing people to act with attachment. He hints at the dualistic perception that binds souls, pointing Arjuna toward realizing his own eternal, detached self behind these veils.

Krishna contrasts the sunlight of knowledge with the shadow of ignorance, which veils the true self. This allegory emphasizes the transformative power of wisdom, showing Arjuna that true knowledge dispels all confusion about self and duty.

Those aligned with the Supreme gain immunity from rebirth. Krishna presents the purity achieved through steady spiritual focus, guiding Arjuna toward understanding the fruits of undivided loyalty to the path of knowledge.
