A while back I ordered a meditation mat and cushion from the DharmaCrafts people. A little card was included with the following printed on it. There was no author cited:
The Human Route
Coming empty-handed, going empty handed - that is human.
When you are born, where do you come from?
When you die, where do you go?
Life is like a floating cloud which appears.
Death is like a floating cloud which disappears.
The floating cloud itself originally does not exist.
Life and death, coming and going, are also like this.
But there is one thing which always remains clear.
It is pure and clear, not depending on life and death.
What, then, is the one pure and clear thing?
