Do you sometime think in clear, abstract, wordless, imageless, concepts?

Perhaps you are right. But, then I have always differentiated between my thoughts and imaginings, and insights and instincts they still seem different. I don't know now I have to go ponder this.

let me know what u come up with :)

that's really interesting. I'll have to pay closer attention and see what I come up with - lol.

hhhhmmm.....I see what you are saying yet I can not agree with this. Many times I have something I have come to call a sub-thought. It starts as an impulse nothing more, then it becomes a feeling almost emotional but not the same emotion we feel when we react to something, then there is this sense of knowing something and no image that I can see (I have tried to no end to find the image and can not.), then if I want to understand the knowing my mind proceeds to associate it with a concept and that concept usually has some abstract visual associated (I have drawn many Salvador Dali like pictures based off this first conceptual image.), the concept proceeds then to get various concrete images and words associated with it, but if I don't care to understand it I can simply act upon it or let it go and all I have is that knowing. A wordless image-less knowing. Sometimes I get what I call intuition too, which also has no word or image. It comes as what I can only describe as a flash of insight. With meditation I have learned that I can actually silence my thoughts for prolonged periods and there by increase the number of these happenings because somehow structured thought actually distracts us from this unstructured experience. At least this is my experience as I understand it. Perhaps thought the image is there and I somehow miss it....
