Each of us was created through sex, and every day we are influenced by sex. Our hormones influence us continually, in our thinking, feeling, and body. Therefore, it is simple logic to recognize that a saint or holy person is a result of a upright, pure sexual life, while a criminal or a liar is the result of a degenerated, impure sexual life. The sexual energy of a saint fills their heart, mind, and body with pure thoughts, pure emotions, and vitalizing energy. The sexual energy of a criminal fills their heart, mind, and body with degenerated thoughts, emotions, and energy. Therefore, if we want a better life, we simply need to learn how to use our sexual energy in a better way. We can do so by understanding the connections between three sciences: sexology, endocrinology, and criminology. Sexology studies love, the most powerful force in human life. It inspires our greatest acts, sustains us in difficult times, gives us hope, inspiration, and purpose. But more than that, love is the power that turns the common person into a superhuman. The sexual energy — which fuels the love of a couple and creates children — is also the wellspring of the love expressed by the greatest human beings, such as Jesus, Buddha, Joan of Arc, etc. While it is well known that serious spiritual seekers preserve their sexual energy for spiritual purposes, science has largely ignored why. The preservation of the sexual energy (called chastity, tantra, alchemy, karezza, coitus interruptus) supercharges the endocrine system and the brain. On the other hand, the worst human beings are always sexual degenerates whose bodies and minds are decayed. Endocrinology studies the active agent of sex: our endocrine system, the incredible power of hormones. The hormones not only push us towards sexual activity, they also power the pineal and pituitary glands, which facilitate our ability to imagine, to “see” with our “mind’s eye.” The hormones influence the brain and the heart: when a person is in love, the hormones inspire that love, and raise the quality of life to the highest, while also filling the mind with beautiful visions of the beloved. When a person is afflicted by lust, the hormones saturate the brain and heart with lustful desire and degenerated, selfish fantasies. For the suprasexual, the hormones are the vitalizing influence that regenerates the brain and heart, and empowers visions, clairvoyance, conscious dreams, and spiritual powers. For the infrasexual, the hormones — being corrupted by desire, lust, anger, and pride — cloud the mind, degenerate the emotions into selfishness, and hypnotize the consciousness with paranoia, hallucinations, obsessions, fantasies of wealth and power, motivating the person towards crime, violence, rape, etc. This is criminology: the science that examines how desire, expressed through mental images, is the basis of crime. If we want to guide our life towards higher level, or if we want to help those who suffer — such as criminals, the mentally ill, the paranoids, or the depressed — then we need to understand how to use the sexual energy in a restorative and regenerating way.
