On a more philosophical note, to me looking down, is looking at energy from behind, energy from the past, it all comes from above, and flows to below in nature. When we look down, we are looking at life as it has degenerated to, all depending on other things that lived in the past, in other words, death. The deeper we go there, the more generations of things that lived in the past are depended on, by the life-forns existing there.
When we look up, we see energy coming at us from source, we are looking at the front of it, the future, life, not death.
If we want to be positive, seeking to enhance life, I think we gotta be more inclined to look up, rather than looking down :) Thanks for making me think about it!
