Acceptance - the opposite of childish resistance

I came across this quote the other day, which reminds me of my grandmother’s saying ‘What cannot be cured, must be endured’ but rephrased in a more positive way:

What cannot be avoided, t'were childish weakness to lament or fear. Shakespeare/De Vere

Here we have acceptance in a nutshell: to be a man is to face the inevitable bravely without complaining that it should be otherwise. Shake-speare always has the knack of putting his finger on the crux of the matter, doesn’t he?
When we don’t face up to what can’t be avoided, we are in resistance mode. We are wasting energy bewailing our fate. We are hanging on to an idea of reality that doesn’t exist any more, if it ever did. We are not adapting to the situation at hand and we are not considering what the situation at hand demands of us. We are being childish instead of being men, or women. The feeling of a weight falling off your shoulders when you accept something is nothing more than the relaxing, the abandoning, of this effort of false resistance.
We saw the value of seeing clearly in Decrease and other posts about sincerity:

Decrease does not under all circumstances mean something bad. Increase and decrease come in their own time. What matters here is to understand the time and not to try to cover up poverty with empty pretence. If a time of scanty resources brings out an inner truth, one must not feel ashamed of simplicity. For simplicity is then the very thing needed to provide inner strength for further undertakings. I Ching

We tried complicated. We thought we had complicated covered. We were wrong. We got hurt. Now we have to face simple, even though we don’t want to. But the funny thing is that simple is what we need. Simple was staring us in the face all along but we didn’t want to see it. Now we have no choice but to face it - but its OK. Simple is how we move on from here. So let’s get over it. Let’s embrace it. Let’s accept it.

The survival of the fittest is the ageless law of nature, but the fittest are rarely the strong. The fittest are those endowed with the qualifications for adaptation, the ability to accept the inevitable and conform to the unavoidable, to harmonize with existing or changing conditions. Dave E. Smalley

A man shares his days with hunger, thirst, and cold, with the good times and the bad, and the first part of being a man is to understand that. Louis L’Amour
