I realized that most thoughts are impersonal happenings, like self-assembling machines. Unless we train ourselves, the thoughts passing through our mind have little involvement with our will. It is strange to realize that even our own thoughts pass by like scenery out the window of a bus, a bus we took by accident while trying to get somewhere else. Most of the time, thinking is an autonomous process, something that happens outside of our control. This perception of machine-like quality of the self is something many people discover, then try to overcome, through meditation.
