Anger caused self-combustion, and so would grief.
What did this mean?
It showed that the cause of the self-combustion came from a person's fluctuations of emotions.
Once the fluctuations were too intense, self-combustion determinants would be activated.
Self-combustion determinants were the source, a barrel of oil, and pleasure, anger, sorrow, and joy were the matchsticks.
If the matchsticks were not lit, the oil would not burn.
With this inference, the problem returned to square one.
What was the self-combustion determinant?
Where did it come from? How did it come about? When did it enter the human body? How did it enter the human body? Did everyone have it, or did only a few people have it?
There wasn't an answer to any of the questions.
And without knowing the answers, the self-combustions wouldn't stop!
The matter would only get worse.
…
And that was indeed the case.
