We tend to lend objects the gift of agency. Computers don't want to work, and the fire is playing up. :) Do thoughts come on their own? Observe and pay attention to precisely what is noticed.
There are many ways in which thoughts seem to arise, sometimes seemingly in response to memory or other triggers, and sometimes at random, but I don't know where the specific thoughts come from.
In discussing with my wife a film we watched last night, I recalled different scenes that stood out for me, then shared my observations. I don't know why I recalled those particular scenes nor why my particular thought/observations arose, but they seem to fit within the parameters of what this particular body/mind finds fascinating.
When there are goals that I desire, (projects, friendships, etc.,) I notice that thoughts come up which seem to move me closer to those goals
Sometimes in a work environment, I’ll surround myself with the components/obstacles of the goal at hand - designs, data, timelines, people - and marinate in them, and after some time, solutions will present themselves. But, sometimes solutions pop up without the preliminarily work, like in the shower, and worry seems to have no bearing on the availability of in-the-moment thought/solutions either.
Or, I will unintentionally see, hear or smell something when I’m not involved in specific problem-solving that seem to trigger a thought related to one of those goals that then moves the game piece forward. But the fact that a particular thought is triggered seems to have no relation to any intention on my part. There is desire, though.
Another category are thoughts that randomly arise - ideas about something completely new - that seem to be unrelated to anything I’m working towards or were exposed to, but that do seem to stay within the orbit of the world of this body/mind.
So, I can't say that thoughts arise on their own, under their own power, but only that I don't seem to have much to do with it, nor know how or why they arise.
You say "I have no control over when they come..." etc, but the point is: What is the nature of this "I"? Is it in any position to control anything? - what with being completely fictional n'all!
You got me there. “I” can’t control anything, any more than the Easter bunny can bring eggs.
But here it’s easy to see how the “I” is believed in. When this body/mind flowers in a unique way, through thought or other manifestations, that uniqueness is taken to be a “me.”
When you are ready: wander into the possibility that a thinker and doer do indeed exist, and you were wrong to ever think they were fictional.
Not sure what you mean here. If a thinker and doer do exist, but the “I” is fictional, then that thinker/doer would be this body/mind, but absent the ownership, the claiming?
