✣ "Mer" means Light. "Ka" means Spirit. "Ba" means Body. Mer-Ka-Ba means the spirit/body surrounded by counter-rotating fields of light, (wheels within wheels), spirals of energy as in DNA, which transports spirit/body from one dimension to another.
Psalm 145:19 The 20th letter, reish, has a bent shape like that of a tzadhe, also bowed in repentance to G-d. The reason one might ask for forgiveness is to repent for sinful behavior. The title "rasha," implying a "wicked person," begins with a reish. the repentant pose of the reish shows that even a rasha can return to G-d. When a person completely repents, they become a "rosh," a leader as opposed to a follower. [last paragraph is awesome, won't fit. :(]
