The distance is great from the firm belief to the realization from concrete experience

I ask you to believe nothing that you cannot verify for yourself.

Faith is something you believe in the UNSEEN before you SEE to believe it!

The only way to know something absolutely is to experience it for yourself; anything less is theory, speculation, and belief.

A traveller must buy his own experience, and success or failure depends mainly on personal idiosyncrasies.

You can't step twice into the same river.
