What is the main message of Bhagavad Gita?

The following is an excerpt from a samvaad (dialogue) session with Acharya Prashant.

Bhagavad Gita

यस्त्वात्मरतिरेव स्यादात्मतृप्तश्च मानवः । आत्मन्येव च सन्तुष्टस्तस्य कार्यं न विद्यते ॥

न बुद्धिभेदं जनयेदज्ञानां कर्मसङ्गिनाम । जोषयेत्सर्वकर्माणि विद्वान्युक्तः समाचरन ॥

The man who rejoices only in the Self and is satisfied with the Self, and is contented only in the Self — for him there is no duty to perform.

The wise man established in the Self should not unsettle the mind of the ignorant one attached to action, but should get them to perform all their duties while dually performing his own duties.

— Shrimad Bhagavad Gita, Chapter 3, Verse 17 and 26

The call for right action!

Questioner (Q) : In verse 17, Shri Krishna says that there is no duty to perform for the one who rejoices only in the Self.
