As soon as someone starts talkin' about nature some body always gotta bring up Darwin. If you think he was the first cat to use nature as a way of understanding the processes of life you need to run to your local library. Let me take a quote from one my essential readings The Art of Peace.

"Now and again, it is necessary to seclude yourself among deep mountains and hidden valleys to restore your link to the source of life. Breathe in and let yourself soar to the ends of the universe; breathe out and bring the cosmos back inside. Next, breathe up all fecundity and vibrancy of the earth. Finally, blend the breath of heaven and the breath of earth with your own, becoming the Breath of Life itself."

We cannot just go by the accounts of our forefathers we must complie our own manuscripts to pass down, like the wisemen of antiquity. The reason why the generations are becoming so stagnant is that the wisdom we apply (while in many ways timeless) is becoming more and more outdated. We must take a pro-active stance to spirituality and scribe a definite spiritual manual for our times or be stuck in a forgotten time..
