The secret of the positive mitzvot, the commandments to perform certain actions, lies, in a manner of speaking, in the activization of the limbs of the body, in certain movements and certain ways of doing things which are congruous with higher realities and higher relationships in other worlds.
In fact, every movement, every gesture, every habitual pattern, and every isolated act that man does with his body has an effect in whole systems of essences in other dimensions with and against one another.
–Rabbi Adin Steinsaltz
