Why does surrender make a person free from worry?
Surrender means being carefree
The stronger your surrender, the more carefree you become. Worry about your own welfare goes with a missing connection, and you should become so carefree that even the name of your own worry ends.
The stronger the surrender, the greater the carefree-ness. Be sure of this: we have taken on the burden of how our own welfare and well-being will happen.
