What does the Bhagavad Gita say about becoming fearless?
Detachment ends fear
Krishna says in Gita 12.15 that his devotees who do not fear are very dear to him. The cause of fear is attachment, and the moment we become detached from material objects we become fearless.
The cause of fear and anxiety is attachment; it makes us yearn for the object of attachment and fear separation from it.
