Hi alan, I can't easily quote with this phone...so... I read that you (believe that) you can have visual impressions, sounds, thought-impressions, all at once. I think you should investigate this more thoroughly. Because as I understand it, that's how things can appear, but not how they really are. You can't actually see and hear at the same instant. What happens is that the mind moves so quickly from one thing to another, such that, as in a movie, the many frames are perceived as one, continuous experience.
But don't think you are alone, I'm similarly engaged in trying to see through this identification with conscious awareness as 'the one who knows' -with the underlying assumption of this being our 'authentic, real self' there, u know what I mean? But maybe instead of construing 'knower', we should just cultivate 'knowing'...
This work might require patient, consistent application of the entire eightfold path for some time.
Keep treading...
