Classical Vedanta · part of the Mahabharata
Bhagavad Gita 18.66
The final instruction — abandon all else and take refuge
सर्वधर्मान्परित्यज्य मामेकं शरणं व्रज। अहं त्वा सर्वपापेभ्यो मोक्षयिष्यामि मा शुचः॥
Abandon all varieties of dharma and simply surrender unto Me. I shall deliver you from all sinful reactions. Do not fear.
What this verse points to
This is the Gita's concluding counsel, the verse the tradition calls the charama shloka, and its force is in what it releases Arjuna from: the exhausting attempt to work out every obligation correctly before acting at all.
Commentators have read the surrender it asks for in very different ways, and the differences are real. What they agree on is the relief in it — the end of carrying the whole calculation alone.
Sit with it
Sit with one decision you have been over-analysing. Instead of solving it again, set it down for the length of the sit.
About the Bhagavad Gita
The Bhagavad Gita is a 700-verse dialogue set on the battlefield of Kurukshetra, in which Krishna counsels the warrior Arjuna at the moment he refuses to fight. Across eighteen chapters it draws together the paths of action, devotion, and knowledge into a single teaching on how to act without being bound by action. It sits inside the Bhishma Parva of the Mahabharata and has been the most widely commented-upon text in the Vedantic tradition, from Shankara onward.
