All that is needed is to feel whatever you may be feeling without making yourself, the other, or life wrong.
Yes, you have known these words and, on one level, understood the meaning. You, however, have yet to know deeply how constant the “make wrong” is, and will continue to be for some time.
There is a bigger part of you that still only wants a solution to a problem. The internal belief that there is a problem interferes with your natural life flow.
Picture a stream coming upon a rock. Feel into the stream; imagine the stream stopping, refusing to move because there is a rock in “its way!” This is what you do, energetically, when a feeling comes into you that you have made wrong at one time or another. Or, you have made yourself wrong for simply having this feeling.
It is, indeed, a sin to not value yourself. You cannot value yourself while making yourself wrong with every wave of emotion. This is antithetical. To honor yourself means to allow what is in you at the present moment. Do not reject anything that comes. This does not mean to let your ego run with whatever comes; that would truly be insanity. But so is rejecting what comes.
In your dualistic present state, you cannot see, hear, feel and know that if one thing exists, its opposite also exists. The two seemingly opposites are one and the same; it is just not experienced because it is rejected.
You cannot love without knowing where and why you hate. Feel into the hate so that you can better understand where it originated. Then, and only then, can you reclaim that part of you that got lost along the way.
Yes, you were hurt. As were all human beings. Painfully so. Not because you were/are innately bad and wrong, or because life is punishing. Not at all. Only because, through this pain, you are propelled towards finding yourself.
Otherwise, be honest, you would not be bothered. Motivation is hard to come by in human nature. Not everyone is blessed with a huge amount. Most people are only motivated externally. To be motivated internally requires something. This is the purpose of pain, simply to motivate you. If it hurts for you to hate so much, look into the hate rather than away.
Do not project the hate outward. It belongs to you. If you are willing to feel the pain under this hate, you will discover a deep love and resurrect this most powerful spiritual energy. It will never be handed to you, no matter how much you stomp your feet. You cannot do enough in the external world to earn this love you long for; it is already inside of you. It is buried under your own rejection of yourself. You could not help but reject what you could not understand at one time. Now, you have the tools to reconstruct your belief system. You deserve profound respect, innately.
With love and appreciation. There is gold there. Keep digging.
