Bhagavad Gita, Chapter 3, Verse 31

Those men who constantly practise this teaching of Mine, full of faith and without cavil, they too are freed from the bonds of work.

Taking this seriously, without cynicism, is itself what starts loosening the grip.

Faith here isn't blind belief, it's a willingness to actually try what's being offered instead of dismissing it out of skepticism or resentment. That openness is what makes the teaching capable of doing anything at all.
