Merle, We don't "have to make sense of our experiences". We could just sit in deep samadhi until we died.
We choose to intellectualize our experiences and use these perceptions as the basis for making decisions about what actions to take and what not to take. Although I admit that for most of us it's really not a choice since we aren't aware there is an alternative. Anyway, all that's our Human Nature at work, not Buddha Nature. ...Bill! --- In Zen_Forum@yahoogroups.com, Merle Lester <merlewiitpom@...> wrote: > > > >  bill..we have to make sense of our experiences... and if you say the > intellect distorts reality..how else pray are you going to operate?..there is > no other system...merle > > >  > Merle, > > If you are color-blind or totally blind it makes no difference.
