In Tibet they say that this Universe is presented to us by our mind as a reflection like a moon on water. The world around us is a refection on the screen of our mind from our eyes looking at the real thing outside of us. We never see the real thing, only its reflection in our mind.
When we enjoy this world and live in the Now, we enjoy right now for whatever appears right now. There is no distraction from thinking about the past or the future. This is Be Here Now.
