But it is important to realize we are all trapped in mental constructs, and so we separate ourselves from reality; the whole world loses its aliveness-or, rather, we lose our ability to sense that aliveness, the sacredness of nature. When we approach nature through the conceptualizing mind, we see a forest as a commodity, a concept. We no longer see it for what it truly is, but for what we want to use it as. It is reduced. This is how it becomes possible for humans to destroy the planet without realizing what they are doing.
Eckhart TolleOnce you have had a glimpse of awareness or Presence, you know it firsthand. It is no longer just a concept in your mind.
