People have different natural traits. Some are irritable and prone to anger. Other are stable and never become angry, or are rarely provoked to anger, only once every few yeas.
Some people are very proud, while others are humble.
Some are controlled by desire and will never be satisfied in their search for pleasure. Others have pure hearts and will not desire even their basic necessities. Others seek little. A small amount, less than required for their needs, is enough for them, and they will not go out to seek to earn their sustenance. Others spend their money lavishly.
