Even though these great monks under Buddha, they already attained Arhat and wisdom, but they still had some ego left. Do you understand me? That is the problem. The ego is the one who makes you judge wrongly and think differently than you should. "The Buddha wanted to save his life. So, of course, the old man was feeling happy, happy, all the sorrow and trouble, gone, and then he followed Buddha back to the ashram. So he called Maudgalyayana to come and told him that he has to teach this man, make him a monk and then train him into monkhood. He probably repeated it. So he knew it, very fast."
