Resignation is not surrender. You don't need to accept an undesirable or unpleasant life situation. Nor do you need to deceive yourself and say that there is nothing wrong with being stuck in the mud. No.
You recognize fully that you want to get out of it. You then narrow your attention down to the present moment without mentally labeling it in any way. This means that there is no judgment of the Now. Therefore, there is no resistance, no emotional negativity. You accept the "isness" of this moment. Then you take action and do all that you can to get out of the mud. Such action I call positive action. It is far more effective than negative action, which arises out of anger, despair, or frustration. Until you achieve the desired result, you continue to practice surrender by refraining from labeling the Now.
Let me give you a visual analogy to illustrate the point I am malting. You are walking along a path at night, surrounded by a thick fog. But you have a powerful flashlight that cuts through the fog and creates a narrow, clear space in front of you. The fog is your life situation, which includes past and future; the flashlight is your conscious presence; the clear space is the Now.
