Magid Rakhtza suggests that the transgressor's tikun [repair] is done through Torah [law], for "This is the law of the burnt-offering…of the sin-offering" atones all transgressions, and keeps the evil inclination and the sitra akhra away, for "I created an evil inclination and I created Torah as its antidote". This is what is meant by magid, it refers to the Torah, which is rakhtza [washing]: Through Torah one is cleansed from all transgressions.
