There is a story in India. It is about a little bird. This little bird always watched the moon whenever it was visible. It kept its eyes on the moon and never stopped! It even forgot to drink water. At that time, another bird flew over and saw that the little bied was very thirsty and had became very dry, and so it said, "Why don't you go and drink some water?"

The little bird replied, "If I went and drank some water, then at that moment, I wouldn't be able to see the moon." It was afraid that it wouldn't see the moon when it lowered its head to drink water. If we could think of God to this extent, we would definitely arrain Buddhahood, and be one with God!
