You don't need strength to let go of something. What you really need is understanding.
Know that everything is in perfect order whether you understand it or not.
See that any time you feel pained or defeated, it is only because you insist on clinging to what doesn't work. Dare to let go and you won't lose a thing except for a punishing idea.
Letting go, at its heart, is an act of agreement with Life.
To be more aware, we need only listen for and let go of the thoughts which steal our attention.
The secret self knows the anguish of our attachments and assures us that letting go of what we think we must have to be happy is the same as letting go of our unhappiness.
