Thoughts Behold You.

 All the different movements of religion, science, philosophy, their "movements" and "schools" through time, the supposed "advancement" from one age to the next.

The way we learn it in school, we start with the Egyptians or Greeks, they set the foundation, and then history is a conversation/battle between what was believed, what is currently believed, what should be believed, and what will be believed.

The "history of scientific thought" is the best example of this. We think of it like a natural evolution or progression, people pushing for changes, but it isn't like this at all, the people don't push, the ideas themselves do.

History only shows what thoughts and types of thought possessed those people at that time.
We are currently possessed by all sorts of ideas and metaphysical "truths" which we have unconsciously and consciously absorbed through our culture and circumstance. We do not have thoughts, thoughts have us. If we can see this, we can reduce their grip. We can be like the lion tamer, with hoop and whip. Choosing which thoughts to let leap, thoughts which are better kept back, and thoughts/beliefs that need to be purged and released.

Our biological perceptual apparatus is so sensitive and suggestible, that as one enters the ring and begins to orchestrate the lions of thought, organizing, and releasing, that one's very perceptions of the world, and one's series of feelings change almost immediately.

The world opens up.
