The Maggid of Mezeritch, the successor of the Ba’al Shem Tov, teaches that the verse "A woman of valor is the crown of her husband" alludes to the form of the letter zayin. The previous letter, vav, portrays the or yashar ("straight light") descending from God into the worlds. The zayin, whose form is similar to a vav, though with a crown on top, reflects the or yashar of the vav as or chozer ("returning light"). Or chozer ascends with such great force that it reaches a higher state of consciousness than that of the revealed origin-point of the or yashar. When reaching the initially superconscious realm of keter (the "crown"), it broadens its awareness to both the right and the left. In truth "there is no left in that Ancient One [the level of keter], for all is right." This means that the awe of God (left) at this initially superconscious level is indistinguishable, in its nature to cling directly to God, from the highest manifestation of the love of God (right).
The experience of or chozer, subsequent to the consummation of the creative process inherent in or yashar, the creation of man on the sixth day, is the secret of the seventh day of Creation--Shabbat. The Shabbat Queen" who, in general, signifies woman in relation to man--"the woman of valor is the crown of her husband"-- has the power to reveal in her husband his own superconscious crown, the experience of serene pleasure and sublime will innate in the day of Shabbat.
"Who is a good [literally, "kosher"] woman? She who does her husband’s will." Chassidut explains that the word "does" also means "rectifies," as said in the completion of the account of Creation (the seal of the seventh day, Shabbat): "that which God created to do"-- "to do" in the sense of "to rectify" (thus implying that God has given us the task to consummate the rectification of His Creation), as explained by the Sages. Thus the "kosher woman" is she who rectifies her husband’s will by elevating him to ever new awareness of previously superconscious realms of soul.
