Resh may be found after a person's name on a gravestone to indicate that they were a rabbi or to indicate the other use of rav, as a generic term for a teacher or a personal spiritual guide.
The Talmud maintains that resh stands for rasha', evil. In the Passover hagada' one of the four sons is evil. The other three ask their parents for an explanation "ki ishalcha bincha", "when your children ask you" (Deuteronomy 6:20), while the evil one tells his parents "ki yomeroo aleychem beenchem", "and when your children tell you" (Exodus 12:26), in such a way as to disregards the Passover commandaments. When there is faith, there are no more questions, when there is no faith there are no more answers. (source: Choifetz Haym")
Resh is a container, just as bet (2) and kaf (20) are containers. But while bet and kaf represents forms such as a house or a spoon, resh (200) represents containing the infinite, exponential growth. It also represents the constant transition, flow and change of life. It is like a constant flow of energy, breaking through, breaking down into pieces, and building anew.
