It is not polite to point out that people, if they do not have productive outlets, turn a little… nuts.
Little girls crave dolls because they are driven to invest in others, and a doll will fill the gap. The desire to take care of babies is a deeply healthy and beautiful spiritual hunger; but when people do not marry and have children, then things go sideways. And I am not just talking about the inevitable cats: those same energies, when they loop back inward instead of into a marriage and children, become peculiar food issues and invented “nocebo” allergies. Older single women are far more likely to be generally unwell than their peers.
The power our minds wield over our bodies is prodigious: anyone is capable of making themselves ill purely psychosomatically. But the only reason we do so is when we lack healthy targets for our energies and potential.
The antidote to this problem is to be in healthy and busy relationships. The results are pretty amazing. When we are invested in others, and needed by them, then we think of ourselves less. This is why active mothers are much less likely to be ill than are single women. Their children need them. We can rise to the occasion when we are needed, even to the extent of pushing other ailments out of sight and mind. When the soul is truly busy, the body rightly takes a back seat.
The challenge we all face is that, as much as we may know that relationships and being spiritually productive is the right way to go, most of our inputs are physical, and drag us in the opposite direction. We see, for example, what makes a person physically attractive long before we can begin to recognize the non-physical attributes that ideally make them more than a sack of meat.
And so unless we force ourselves to think of higher order things (like souls and ideas and concepts), we are constantly sucked back down into the physical realm.
Torah Judaism thematically tries very hard to keep people thinking about positive and holy things, to keep us from obsessing over our physical bodies and their weaknesses and processes. For us, bodies are nothing more than tools, and we should never confuse the tool with the craftsman wielding it.
Torah commandments are consistent in this direction. Thus, both male and female bodily emissions, whether healthy or not, are never combined with spiritual elevation. We may physically be animals, but we always aspire to aim higher than our animal selves.
Similarly, we dress modestly to limit the exposure of our bodies. Intimacy is only for exclusive monogamous relationships, and it is never publicly on display. We also, unlike many other cultures and religions, never use mixed dance as part of worship: dancing may be joyful, but it inevitably distracts us from spiritual elevation.
And it is why priests cannot serve if they have a blemish that would lead them (or others) to identify them by their physical selves, instead of their spiritual ability to help connect mankind and G-d. The Tabernacle is no place for us to be reminded of our physical, animal selves.
The human soul/mind is capable of touching the divine, which means there is always room to grow. We try to harness our minds and invest in human and divine connections, because our navels, as interesting as they might be, are always dead ends.
