The Gita begins with a man frozen by fear, and does not shame him for it. Its treatment of fear is to move his sense of identity to something that cannot be destroyed.
The ancient teaching
“Weapons do not cut it, fire does not burn it, waters do not wet it, wind does not dry it.”
ParaphraseBhagavad Gita 2.23, paraphrased from standard translations
What does this mean today?
Most fear is a fear of loss: of standing, of love, of the picture we have of our life. The Gita asks a blunt question — is what you fear losing actually you?
You do not have to accept the metaphysics for the exercise to work. Naming what cannot be taken makes the fear smaller and the next action possible.
