Excerpt From
The Great Causes Discourse
Mahā Nidāna Sutta  (DN 15)

Aging-&-Death

“‘From birth as a requisite condition comes aging-&-death.’ Thus it has been said. And this is the way to understand how from birth as a requisite condition come aging & death. If there were no birth at all, in any way, of anything anywhere—i.e., of devas in the state of devas, of celestials in the state of celestials, of spirits in the state of spirits, of demons in the state of demons, of human beings in the human state, of quadrupeds in the state of quadrupeds, of birds in the state of birds, of snakes in the state of snakes, or of any being in its own state—in the utter absence of birth, from the cessation of birth, would aging-&-death be discerned?”

“No, lord.”

“Thus this is a cause, this is a reason, this is an origination, this is a requisite condition for aging-&-death, i.e., birth.”
