Introspection:

Daydreaming is one of the things you find yourself doing a lot of when hiyaking. You can't help but be inspired by Hawaii's awe-inspiring beauty and realize why most ancient religions worshiped nature. To even a contemporary person the complexities of the interactions between sun, sea, soil, birds, beasts and fishes all seem intelligently designed by some supreme being. Science disagrees, saying environment, random chance and mutations created the world past and present.
Science can never disprove we have souls, and religion can never prove we have souls. Death will decide.
Meanwhile life awaits none. We each hike our own trail or kayak our own river and at our trail or river's terminus, the religious happily expect heaven and the scientists sadly expect nothing. We each get to choose which one sounds better to live by and then die by.
Below are some of my other thoughts, and some others' thoughts. I hope they inspire you to introspection. 
Evolutionary or God-made, that is what makes us uniquely human while awaiting the Decider.

Mine:

• May you blaze new trails and be content knowing you made the path easier for those who follow you.
• The more you climb the more likely you'll fall. So don't fall. Climb or die.
• Happiness and hiking are as life and death. The latter norishes the former.
• Measure your successes not by how many peaks you summit, but by the failures you summit getting there.
• Kulia i ka nu'u (Strive to reach the highest).
• Any fall is a good fall if you walk away from it.
