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 recognise that a saint or holy person is a result of an 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 vitalising 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." 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 is the basis of crime.
