I have sometimes heard the expression "to spin in one's wheels" to refer to a habit of ruminating: coming back to the same thought again and again, and feeling stuck in it. This is such a powerful metaphor, if mainly because it evokes times in my early childhood when something would get stuck in a wheel of one of my toys, and even the slightest piece of dust would cause the car to spin in circles. It's funny how this very same metaphor continues to survive in my memory to this day, as sometimes the image comes up from time to time.
Wheels evoke direction. When we aren't moving like we should, we might get impatient, until we realize that we are making the same mistake of not letting go, and taking the things around us to be solid and substantial. One example of this comes from the Christian concept of "pride", which I actually haven't heard about in a long time. Pride is often equated with the ego, but I see it as the mental trap of thinking there is something substantial within us that we have to defend. When I get caught in the quagmire of hurt, what I do is to put on the protective armor of consoling thoughts, which sooner or later becomes an overprotective armor consisting of all kinds of consolations. These consolations, as comforting as they are, imply a barricading of self against a perceived threatening "sense of the other" which could take the form of any number of hurts. There is nothing wrong with all of this, but soon, we may become so invested in a strong sense of self that we refuse to let go of it even when the "threat'' has disappeared. Then the hardest thing is to let go, and I think this is a form of pride.
Pride can even take the form of thinking that our suffering has ennobled us. We might even hold onto the idea that we overcame something terrible in the past to make us who we are now. I think this is valuable to a certain degree, but it also means that I identify myself as fighting against some adversity, and this creates an opposition of I vs. them.
How we let go of pride is to realize that there is nothing much to defend. I think this takes many years of realizing that all the scrapes we get into are temporary experiences. What seems real today gradually recedes into the distant past later.
