Thoughts

[What is hooked into so that a specific thought arises rather than another?]

Thoughts are thoughts. You can make a treatise out of why one appears over another, but what is the point? To know where they originate from is critical. Who makes them? Who sends them? Where do they go? These answers will find yourself in the position to rectify much.

[Where do thoughts come from? How can this be seen and experienced?]

From the depths of one's being these originate, not as owners of the moment, but rather messengers of the meager trappings of the soul. They come, they go, they inform. The ego depends on constant fuel. It must excite itself, otherwise it dies. Thoughts and emotions serve this end if one owns them, and most do. They are fleeting and inasmuch require no care at all. They are here for the moment, gone the next. What they impact is significant only in that it is a part of experience that is designed to navigate one through the assorted ways in which you interact. They are signals, not to be caught up in, but rather looked at and let go. There is no impact unless they are grasped and hung onto, or believed to be a real state of things. Let them go. They do their job to inform, don't misuse them by claiming ownership. They are messengers from within.
