Everything that happens to us is a mixture of good and bad. This farmer apparently doesn't believe in free will. Man is so narrow-minded and naive, yet he claims to know it all. Although the story may provide relief to people who believe that a superior being is looking out for us, it in effect tells us to accept our situation without trying to change it. Que sera, sera.
Life is a mystery.
Don't take it for granted. Accept it, and try to enjoy the ride. This farmer has mastered the art of letting go and letting life take its course. But he also seems to be a bit unfeeling. I don't think that has to be sacrificed for serenity.
