(Statue of Shaka/Buddha)
“Shaka (Buddha)” exemplifies someone that is supremely knowledgeable. He is so perfect that nobody else can preach or teach him. No way! Today’s proverb teaches you that it is totally ridiculous of you if you try to preach or teach Shaka or someone that is 100 times as knowledgeable as you are. Still you know at least one or two who tend to preach or teach others, don’t you?
