Unprincipled Conduct
Then a certain brahmin went up to the Buddha and exchanged greetings with him.When the greetings and polite conversation were over, he sat down to one side and said to the Buddha:
“What is the cause, Master Gotama, what is the reason why some sentient beings, when their body breaks up, after death, are reborn in a place of loss, a bad place, the underworld, hell?”
“Unprincipled and immoral conduct is the reason why some sentient beings, when their body breaks up, after death, are reborn in a place of loss, a bad place, the underworld, hell.”
“But what is the cause, Master Gotama, what is the reason why some sentient beings, when their body breaks up, after death, are reborn in a good place, a heavenly realm?”
“Principled and moral conduct is the reason why some sentient beings, when their body breaks up, after death, are reborn in a good place, a heavenly realm.”
“I don’t understand the detailed meaning of what Master Gotama has said in brief.
Please, Master Gotama, teach me this matter so I can understand the detailed meaning.”
“Well then, brahmin, listen and pay close attention, I will speak.”
“Yes, sir,” the brahmin replied.
The Buddha said this:
“Brahmin, unprincipled and immoral conduct is threefold by way of body,
fourfold by way of speech,
