Chesed L’ Avraham (Maayin 4: Nahar 48): You should know that Shir HaShirim is concerned with the issue of chasan and kallah. The chasan alludes to the Shechinah (Divine Presence) and the kallah to the Jewish people. It is known that all the attributes of G‑d are measure for measure. In other words to the degree that a person conducts himself in relationship to G‑d so too will his wife conduct herself in relationship to him. That is why our Sages say that if a man merits it then his wife assists him but if he doesn’t merit it then she will be his opponent. She will rebel against him when he rebels against G‑d. But this principle is only relevant for tzadikim. Consequently every ben Torah whose wife does not obey him has no right to complain because he brought this on himself. In contrast, the wicked have their lives conducted on the basis of natural phenomenon and their wives obey them when they are afraid of them.
You should know that it is not appropriate that the wife should be seated on the right side of her husband but only on the left side. However the kallah at the chupah at the time when the sheva berachos (7 blessings) are being recited, it is necessay for the kallah to be standing on the right side of the chasan...The reason for this that there is a major segula (remedy) that if the chasan is careful to place his right foot on the kallah’s left foot at the time of the sheva berachos, he that succeeds at this is more likely to be able to rule over his wife for his whole life and she will be subservient to him and obedient to his every word. However if the kallah is careful to place her left foot on the chasan’s right foot – then she will rule over him all her life. There was an incident in which the chasan placed his right foot on the left foot of his kallah during sheva berachos in order that he should rule over her. When the kallah told her father about this he taught her and cautioned her that the time of the first intercourse that she should ask the chasan to bring to her a pitcher of water and by means of this it would cause that she should rule over him all of her day. This is a segula (remedy) to nullify the effects of the segula (remedy) of placing his right foot to rule over the kallah....
The basis of this segula is that the woman is from the left side and her conduct is based on the strict level of right and wrong which is difficult. In such a house run by the strict level of justice there is no lack of sickness and poverty and something else. Happy is the household that is run by the man because it is as if it is run by the attribute of mercy. Consequently there will be no bad happenings that will happen in that household because the Shechina (Divine Presence) is manifest in a house which is conducted according to the attribute of mercy. You should also know that there are three types of gevura (might) in man. The first is the might which is involved in conquering many lands. The second type is even greater than the first and is the gevura in controlling his wife. The third which is the hardest is the gevura in controlling his evil inclination.
