A man saw a snake dying in flames and decided to rescue it from the fire. As soon as he caught it, the snake bit him, causing extreme pain. The man immediately threw the snake away, and the reptile fell back into the burning flames.
At this time, the man looked around, found a metal rod, and used it to remove the snake from the flames, saving his life.
Another man who saw what had happened approached the man and asked him, "This snake has bitten you!" Why do you want to save his life?
The man replied: "The nature of the snake is to bite, but this does not change my nature, it is helpful."
Don't change your nature just because someone hurt you. Don't lose your mind, but learn to act with caution.
