Dutiyabodhi Sutta
Thus I have heard—
Once, the Awakened One was living at Uruvelā,
On the bank of the river Nerañjara,
At the root of the tree of Awakening,
Just after his complete awakening.
On that occasion,
The Awakened One sat in one posture for seven days,
Experiencing the bliss of freedom.
Then, when the week had passed
He emerged from this Samādhi,
And, in the second part of the night,
Paid careful attention to the regressing chain of causality:[1]
When there is not this, that does not come to be,
When this cease, that also ceases, that is—[2]
(1) When lack of awareness ceases, mental activities cease,
(2) When mental activities cease, consciousness ceases,
(3) When consciousness ceases, mind and body cease,
(4) When mind and body cease, the six senses cease,
(5) When the six senses cease, contact ceases,
(6) When contact ceases, experience ceases,
(7) When experience ceases, wanting ceases,
(8) When wanting ceases, attachment ceases,
(9) When attachment ceases, the sense of self cease,
(10) When the sense of self ceases, renewed existence ceases,
(11) When renewed existence ceases,
(12) Aging and death cease,
And of sorrow, sadness, trouble, depression and anxiety all cease.
This is how this whole mass of trouble ceases.
Then, having understood this,
the Awakened One let out this joyful revelation:
“Surely, when the nature of things becomes clear,
To the devoted meditating Brāhmaṇa,
At that time, all doubts vanish,
When one understands the breaking up of conditions.” [3]
