How does one accept the unacceptable? This seems to be an important question to answer if you are to live peacefully in the world. Most people don't accept things as they are. They fight and strive to make the world meet their expectations. They get upset when things don't go their way and hold on to grudges and the resulting pain for a long long time.
Do you want to live in peace, regardless of what is happening to you and around you? If so, then you must understand what it means to accept the unacceptable. You must see clearly what causes you to refuse acceptance. Once you see this clearly then you can finally make the choice to accept.
What does it mean to accept something? Remember a time that you encountered something that was hard to accept... something that took time to accept. What happened within you that allowed this previously unaccepted thing to become accepted? Isn't it clear that in most cases you don't actually accept the thing? You simply allowed your memory of the thing to fade enough so that the pain no longer bothered you. You know this is true because when you recall the thing that caused you so much pain, the pain is still there waiting for you. That isn't acceptance at all... it's avoidance. True acceptance is without pain.
To truly accept something you must understand what unacceptance is. Unacceptance is a state of conflict between your image of the world and how the world actually is. Reality is doing something that you disagree with and steadfastly refuse to allow to be as it is. This refusal is, of course, completely unimportant to reality. Reality is doing what it's doing regardless of what you want to happen.
Whatever it is that you cannot accept, the root of your unacceptance is incorrect thinking. Your image is distorted and out of alignment with reality. This lack of alignment brings you to create all manner of negative emotions within you: anger, jealousy, resentment, disgust, sadness and depression. Your refusal to allow reality to be what it is is the cause of your pain...
If you want to accept the unacceptable then you must clearly understand that reality is what it is. It cannot be any other way. Put away your hope that reality will be better in the future. Put away your notions that reality is currently wrong. Reality cannot be wrong. Only your thinking about reality is wrong.
If you want to accept the unacceptable then see clearly that there is nothing in reality that needs to be accepted. Acceptance is an illusion born of The Image that you have built and protected for so long. You believe in your image of reality over reality itself. This false belief is your barrier to true acceptance. Simply seeing the true nature of acceptance is the key to rising above the need for acceptance.
See clearly that you have no need to accept anything... that your need for acceptance is a lie that you keep telling yourself... that acceptance is born of your refusal to see reality as it truly is. On glimpsing this you will understand that you cannot accept a thing and all things are already accepted.
