This was said by the Blessed One, said by the Arahant, as I have heard:
“Bhikkhus, for the Tathāgata, the Arahant, the perfectly Awakened One, there are two principles of explaining the Dhamma. What are the two? 1) ‘See |harm::evil, wrong, worthless, bad [pāpaka]| as harm’ — this is the first principle; and 2) ‘Having seen harm as harm, become |disenchanted with::disillusioned with [nibbindati]| it, become |detached from::dispassionate towards [virajjati]| it, and be |released from::freed from [vimuccati]| it’ — this is the second principle.”
The Blessed One spoke on this matter. In this regard, it is said:
“Of the Tathāgata, the Buddha,
who is compassionate towards all beings;
See the two principles,
of explaining the Dhamma.
See this harm [for what it is],
and become disenchanted with it;
With a mind free from attachment,
you will bring an end |of suffering::mild suffering, intense suffering, discomfort, pain, disease, unpleasantness, stress, discontentment, dissatisfaction [dukkhassa]|.”
This matter too was spoken by the Blessed One, as I have heard.
