“The oblivion fear is something else, fear that I won't be able to give anything in exchange for my life. If you don't live a life in service of a greater good, you've gotta at least die a death in service of a greater good, you know? And I fear that I won't get either a life or a death that means anything.”

“Something has spoken to me in the night...and told me that I shall die, I know not where. Saying: "[Death is] to lose the earth you know for greater knowing; to lose the life you have, for greater life; to leave the friends you loved, for greater loving; to find a land more kind than home, more large than earth.”

“You’re not a human being until you value something more than the life of your body. And the greater the thing you live and die for the greater you are.”

“The life you never live is greater than the wealth you never know”
