This is true. But a lot of people also go for the full-scale ego-death thing, seemingly without realizing they could find peace within themselves without the ego part attached to it. Maybe I'm wrong. But there's something altogether enrapturing about the texture of plants, the songs of the birds, the smell of the season, that mountain framed perfectly within the mind's eye.
I often watch my cats and think they seem to appreciate all of this, infinitely and without noticing. While due to evolution through the inflexibility of concepts and thoughts, not-noticing becomes the default state for most humans. It's a shame though as I've found there to be nothing more invigorating of life than this simple (cat-like) appreciation of nature on more than one occasion.
