At Sāvatthī.
“Mendicants, there are these four sides.
What four?
The side of substantial reality, the side of the origin of substantial reality, the side of the cessation of substantial reality, and the side of the practice that leads to the cessation of substantial reality.
And what is the side of substantial reality?
It should be said: the five grasping aggregates.
What five?
That is, the grasping aggregates of form, feeling, perception, choices, and consciousness.
This is called the side of substantial reality.
And what is the side of the origin of substantial reality?
It’s the craving that leads to future lives, mixed up with relishing and greed, taking pleasure wherever it lands. That is,
craving for sensual pleasures, craving to continue existence, and craving to end existence.
This is called the side of the origin of substantial reality.
And what is the side of the cessation of substantial reality?
It’s the fading away and cessation of that very same craving with nothing left over; giving it away, letting it go, releasing it, and not clinging to it.
This is called the side of the cessation of substantial reality.
And what is the side of the practice that leads to the cessation of substantial reality?
It is simply this noble eightfold path, that is:
right view, right thought, right speech, right action, right livelihood, right effort, right mindfulness, and right immersion.
This is called the side of the practice that leads to the cessation of substantial reality.
These are the four sides.”
