Women are inherently materialistic

 Maharal (Sotah 22a): Mishna: ... an ascetic woman (isha perusha) and ascetic wounds ... destroy the world. Women are materialistic and therefore asceticism is not relevant for them i.e., to abstain from that which is permitted to her. That is because abstaining from that which is permitted is abstaining from materialism entirely and this is simply not characteristic of women since they are materialistic therefore it is not normal for her to be ascetic. If you do find a woman who is ascetic it is because she wants to be viewed as a righteous woman and thus it is for her benefit – rather than for spiritual purposes. This is similar to “ascetic wounds” It happens to a person who is excessive with his asceticism and he does things which are inappropriate. This is only done is to make an impression on others rather than for spirituality and thus it is not normal. So not only do these two categories fail to build the world they actually are destructive to the well-being of the world. That is because all things which are excessive - remove a person from the world. Similarly foolish piety which is also mentioned in this Mishna and a cunning wicked person – because they all act inappropriately. It is very necessary to understand these matters in order that a person knows to do acts of piety with wisdom and common sense.
