Sutta 20
Tathā Suttaṁ
True1
Thus have I heard: Once the Exalted One was dwelling near Benares, at Isipatana, in the Deer Park.
2. Monks, these four things are true, not false,2 not alterable.3
What four?
3. The fact of Ill, monks, is true, not false, not changeable.
4. The fact of the arising of Ill, monks, is true, not false, not changeable.
5. The fact of the ceasing of Ill, monks, is true, not false, not changeable.
6. The fact of the practice that leads to the ceasing of Ill, monks, is true, not false, not changeable.
7. These are the four things that are true, not false, not changeable. Wherefore, monks, ye must make an effort to realize: This is Ill, this is the arising of Ill, this is the ceasing of Ill, this is the practice that leads to the ceasing of Ill.
