Arjuna said: O Krishna, what is the mark of a person whose Prajna is steady and merged in superconscious state? How does a person of steady Prajna speak? How does such a person sit and walk?

The Supreme Lord said: When one is completely free from all desires of the mind and is satisfied in the Self by the Self, then one is called a person of steady Prajna, O Arjuna.

A person whose mind is unperturbed by sorrow, who does not crave pleasures, and who is free from attachment, fear, and anger; such a person is called a sage of steady Prajna.
