What is Life

I read a story about a small Dove, who was living in a hole of big building. One day the building got fire, all the birds started fleeing. The Dove saw a watery pot near by, she started to take a drop of water in her beck, fly on the fire and pour the water. Birds who saw this was laughing at her efforts, but she told--it is my duty, I am also an inhabitant of this building. At last the fire was extinguished by constant efforts of all men, none gave any credit to the Dove, but a poet saw her and wrote a poem on her hardwork. But the Dove never knew it, she came back to her room and she was happy that the house is saved. She thanked God and became very happy and started singing.
I think I am also working like this Dove, my works are not remarkable in the context of this big World, but I am happy and cheerful as I am doing my Duty.
Life is Love for me-- Love with no expectation of return.
