You are the only proof for what you believe.
Without you, belief would not be possible.
Investigate all your beliefs until you discover there is no need for belief of any kind.
Belief transforms into a knowing and that knowing equates to being.
To know is to be. To be is to know.
If you chose to die for that, what would be left?
Nothing.
Would you die for nothing?
A man who is willing to die for his beliefs is pathological and a danger to himself and to others.
He is like a man who would lead others on a journey accross the desert on foot without water because he believes oases are real and convinces his followers to believe in him.
