Tulsidas

Tulsidas used to water a certain tree and this pleased the spirit which lived in that tree. One day the spirit appeared to him and offered to give him anything he wanted. Tulsidas wasn't interested in anything else except Lord Rama, so he asked the spirit to show him Rama. The spirit replied, "I can't do that. If I could, I'd see Him myself and be freed from this spirit-form." That is why it is said in the Ramayana, "The soul which receives a human body is extremely fortunate."
