Sakuladayi the Wanderer asked the Buddha: "What is the past and what is the future?"
"Let the past be," answered the Buddha, "and forget the future. I will teach you that which is now."
When this condition is, that condition comes to be,
With the arising of this, that arises,
When this is not here, that does not come into existence,
With the ceasing of this, that too ceases.
