Forgive me if I'm wrong here, but I don't think that English is Coelho's first language. From his flag, I would guess Portuguese?

And I don't mean to be presumptuous either, but I think I have an idea of what he is talking about in seeing more details while stoned.

Take a look at the palm of your hand, for example. You can keep looking closer and closer, and for each new 'thing' you see, you can attach a word. First, 'palm'... you look closer, and you see all these little 'wrinkles'. And if you looked much closer, you'd see 'skin cells', the parts of those cells, the molecules that compose them, and so on. But if you only look closely enough to recognize the wrinkles in your palm as wrinkles, or the molecules as molecules, you miss a lot of detail.

While you could name each line, each cell, and each molecule that you see by its unique position in space, doing so isn't at all necessary in order to experience them.. in fact, most words just seem to be generalizations, a way of simplifying our perceptions in order to more easily communicate them.

It may be impossible for us to get away from conceptualizations, but not necessarily language. I know I have experienced in times of tranquility, often while high but not always, that I'm not thinking in terms of words at all. There's no internal dialogue. And for that reason I find myself more able to recognize details because I don't have the distraction of words. I haven't really learned how to 'shut off' my internal dialogue by choice, as it seems the more I try to the less I can.. but when I'm particularly relaxed and often while I'm drawing or painting, it's definitely easier to slip into that state.
