This book is all about bitachon, the feeling of security that comes from trusting in Hashem. It addresses the subject not only on a theoretical level, but in a practical way that readily and directly improves the quality of our lives the moment we begin to apply what we learn. The more we attain bitachon, the less we worry. The less we worry, the better we feel and the more we're able to redirect our emotional and physical energies toward more productive endeavors, and the more we see enhanced material and spiritual abundance in our lives.
