This Thai vet got his hand and part of his forearm pulled off by a nile Croc in the zoo. He was pulling out tranquilizer darts through a fence but the ol' croc was obviously not as sedated as they thought. Somehow they managed to re-attach his arm after a few hours of surgery.
"So, in this material world you cannot live peacefully. Not at all. There are so many impediments. The scripture says, padam padam yad vipadam: [SB 10.14.58] "At every step there is danger." Danger not only from the lower animals but also from human society. No, our life is not very happy in this material world.
Therefore we should be advanced in inquiring, Why are there so many impediments? How can I become happy? What is the goal of my life? Asking these questions is human life."
