Accepting the truth is the only way to be able to change the truth. Accepting the truth is difficult sometimes. We often think things are other than what they are, and that desire makes us search for evidence that something hidden will come to light and prove things were the way we expected them to be all along.
Meanwhile, had we just accepted events as they happened, unpleasant as they may be, we would have been freed immediately to work on changing things.
Choosing which truth to accept and which to reject is just as bad as rejecting all the truth. We accept pleasant truths and deny unpleasant ones. Or we accept unpleasant truths and deny pleasant ones - you know people that do that, don't you? Go on, tell the truth.
How do you know what the truth is, though?
It's easy, really. Much easier than most would have you believe. The only reason anyone would have you think otherwise is so that they can think otherwise and not be exposed.
Be awake. Pay attention. Ignore nothing that happens to you. Instead of acting as though things will turn out as you expect, give your best effort to make it turn out as you choose. And watch to see how it actually turns out, each action. You'll be wrong at first, because by rejecting the truth in the past, you learned the wrong ideas about how the world works. And it will be painful sometimes. But pain is as much a part of life as joy is. . . that's the truth.
But as you remain alert, as you stay aware, as you stop explaining away the difference between your expectations and events, you learn. And as you learn, the truth becomes clearer. And you feel strong enough to handle whatever pain comes to you.
But you're actually no stronger than you ever were. You just stop wasting your strength on the imaginary, unnecessary battles that result from denying the truth.
