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 first part of the night,
Paid careful attention to the arising chain of causality:
When there is this, that comes to be;
When this arises, there is the arising of that, that is—
- Because of blindness, there are built-in processes,
- Because of built-in processes, there is consciousness,
- Because of consciousness, there is mind and body,
- Because of mind and body, there are the six senses,
- Because of the six senses, there is contact,
- Because of contact, there are felt experiences,
- Because of felt experiences, there is discontent,
- Because of discontent, there is taking,
- Because of taking, there are habit patterns,
- Because of habit patterns, there is [blind] coming into being,
- Because of [blind] coming into being,
- there is aging and death,
And the manifestation of sorrow, sadness, trouble, depression and anxiety.
This is how this whole mass of trouble come to be.
Then, having understood this,
the Awakened One let out this joyful revelation:
Surely, when the nature of things becomes clear,
To the devout meditating Brāhmaṇa,
At that time, all doubts vanish,
As one understands Nature and its cause.
