From the Sufi
A man who had studied much in the schools of wisdom finally died in the fullness of time and found himself at the Gates of Eternity.
An angel of light approached him and said, “Go no further, O mortal, until you have proven to me your worthiness to enter into Paradise!”
But the man answered, “Just a minute, now. First of all, can you prove to me this is a real Heaven, and not just the wishful fantasy of my disordered mind undergoing death?”
Before the angel could reply, a voice from inside the gates shouted:
“Let him in -- he’s one of us!”
