There are two type of thoughts, one is the type that I am using when I am typing this post. It is a horse I am riding, the surf board I am surfing through with. It is so close to the awareness itself, that I sometimes think that is my awareness. The other type are the ones that comes out nowhere. They just come to your mind without being invited.
The second type of thoughts have no goodwill, or intention to be good, or intention to help. They have only intention to live. For a thought to live, it has to get attention from the awareness. Like any other sensation, such thoughts has a short lifespan by themselves. They live in the unconscious world, once in a while across the boundary between the unconscious world and the conscious world. They jump out from the unconscious world, like a fish jump to the air. Such thoughts are like the fire of a match, that will soon die away if not ignites anything else. The thought that can not catch attention dies. The thoughts that successfully catches enough attention get articulated, get resolution, and get pulled out of the muddy unconscious water, into the the conscious free air.
Such thoughts get to live because they arrive at the right time in right situation. They could be totally harmful thoughts looking from the long term perspective, but at that moment they come, they are catchy, attractive, useful, satisfying, etc. Maybe I can say they offer some emotional value at the moment they come. It would be a big mistake to assume thoughts have goodwill to my prosperity just because they come out of my mind. Both good and evil attract attention. That maybe the reason that we shouldn’t develop attachment to our thoughts. Thoughts are good, when used as tools. Take the horse analogy again, it feels good to ride a horse, but not good to be dragged behind a horse by a rope. So don’t trust your thoughts, trust me.
