There are three kinds of people in the world. The first are those who are like letters carved in rock; they easily give way to anger and retain their angry thoughts for a long time. The second are like letters written in sand; they give way to anger also, but their angry thoughts quickly pass away. The third is those who are like letters written in running water; they do not retain their passing thoughts; they let abuse and uncomfortable gossip pass by unnoticed; their minds are always pure and undisturbed.
From the teachings of Buddha
