Mulla Nasruddin has purchased a new house and he planted a beautiful garden, a beautiful lawn. Then a new neighbor moved into the empty house by the side of Mulla’s house. He was enchanted with Mulla’s garden and his lawn. He said, “I would also like to make a beautiful lawn, but how do you know what is grass and what is just weeds?”
Mulla said, “Very simple. You pull out both and throw them. Whatsoever grows again on its own is weeds.”
