Two jewel merchants arrived at a caravanserai in the desert at about the same time one night. Each was quite conscious of the other's presence, and while unloading his camel, one of them could not resist the temptation to let a large pearl fall to the ground as if by accident. It rolled in the direction of the other who, with affected graciousness, picked it up and returned it to its owner saying, "That is a fine pearl you have there, sir. As large and lustrous as they come."
One afternoon Guru Nanak and his company were resting on the banks of the Ganges at Patna. Mardana was idly inspecting a stone he had picked up along the road, thinking of the vast throngs who had come to hear the Guru. "Master," said Mardana, "you teach a way for every person to find liberation. But many of those who listen still seem to spend much of their time in conflict, and in seeking out excitement and other idle pursuits. Why do they waste away their lives so?"
