Both he who possess proofs and he who lacks them are in fact equal in their disconnect from the actual matter. To be persuaded of something is to be detached from it, bereft of the straightforwardness of plainly seeing it.
Parshas Tazria emphasizes the advantage of man's natural effort. By contrast, Parshas Hachodesh relates how Hashem revealed Himself to us in a miraculous way. These two opposite ideas are merged when a Yid realizes that his natural and limited Avodah can be expressed in an unlimited way being that he is connected to Atzmus.
Chukim are the ratzon Hashem as they are in their original source. They are not rendered into a form that also man can understand and are observed only as the means to fulfill Hashem's will. This idea is most seen in the fact that the one involved in preparing the Parah Aduma in order to make another person Tahor, becomes Tamei himself.
When one Yid harms another, the Torah obligates him to give compensation. This is not merely a technical obligation or a mitzvah. It should truly bother a Yid thathe mistreated someone else, and accepting full responsibility.
The theme of our Parsha is "Vayikra - Calling as an expression of affection". This affection includes all segments of Yidden regardless of their level. Purim is observed in such a manner where all Yidden go beyond their spiritual limitations and connect to Hashem.
