Master Kyong Ho and his young disciple, Yong Song, known for his gentleness, went for a walk and passed a stand where boys were selling live frogs. After they walked past, Yong Song stopped and begged his master to rest. Then he went back and with his last remaining coins, bought all of the frogs and set them free. He returned to the master, grinning with pleasure, and said: “Glad we came by this way. I just saved all of those frogs.”
  “That is wonderful,” said the master. “But you are going to hell.”
  Yong Song was crestfallen. “Why? I just freed those frogs.”
  “Yes, you did. And you’re going straight to hell like an arrow.”
  “Why?”
  “You already understand.”
  “No, I do not,” Yong Song implored. “Please teach me.”
  “You say ‘I’ saved those frogs. You say ‘I,’ but this ‘I’ does not exist. Saying this ‘I’ is already a big mistake, but if you keep that I-me-my mind, even though you do something that impresses other people, you go directly to hell.”

Goes to show when we do good deeds for others we should keep it to ourselves...I'm guilty so will try to remember this!
