maybe the greatest wisdom is inside the person who is less likely to behold it, who stays silent and unexposed. yes, true that a wise would not keep the wisdom to himself, but wouldn't it be better to be silent than speaking with wrong deed? for when one speaks wisdom, would it be for other's knowledge or for him to be acknowledged?
always, the hardest of all, to constantly check and re-check the righteousness of our deeds, to not be confused with pride and egocentric needs.
