Various grains, fruits, roots, and for beverage - milk, and pure water openly exposed to air and sun are decidedly the best natural food for man. These, being congenial to the system when taken according to the power of the digestive organs, well chewed and mixed with saliva, are always easily assimilated. Other foods are unnatural to man and being uncongenial to the system are necessarily foreign to it; when they enter the stomach, they are not properly assimilated. Mixed with the blood, they accumulate in the excretory and other organs not properly adapted to them. When they cannot find their way out, they subside in tissue crevices by the law of gravitation; and, being fermented, produce diseases, mental and physical, and ultimately lead to premature death.

Children's development

Experiment also proves that the non irritant diet natural to the vegetarian is, almost without exception, admirably suited to children's development, both physical and mental. Their minds, understanding, will, the principal faculties, temper, and general disposition are also properly developed.

Natural living calms passions

We find that when extraordinary means such as excessive fasting, scourging, or monastic confinement are resorted to for the purpose of suppressing the sexual passions, these means seldom produce the desired effect. Experiment shows, however, that man can easily overcome these passions, the archenemy of morality, by natural living on a nonirritant diet, above referred to; thereby men gain a calmness of mind which every psychologist knows is the most favorable to mental activity and to a clear understanding, as well as to a judicial way of thinking.

Sexual desire

Something more should be said here about the natural instinct of propagation, which is, next to the instinct of self-preservation, the strongest in the animal body. Sexual desire, like all other desires, has a normal and an abnormal or diseased state, the latter resulting only from the foreign matter accumulated by unnatural living as mentioned above. In the sexual desire everyone has a very accurate thermometer to indicate the condition of his health. This desire is forced from its normal state by the irritation of nerves that results from the pressure of foreign matter accumulated in the system, which pressure is exerted on the sexual apparatus and is at first manifested by an increased sexual desire followed by a gradual decrease of potency.

This sexual desire in its normal state makes man quite free from all disturbing lusts, and operates on the organism (awaking a wish for appeasement) only infrequently. Here again experiment shows that this desire, like all other desires, is always normal in individuals who lead a natural life as mentioned.

The root of the tree of life

The sexual organ - the junction of important nerve extremities, particularly of the sympathetic and spinal nerves (the principal nerves of the abdomen) which, through their connection with the brain, are capable of enlivening the whole system is in a sense the root of the tree of life. Man well-instructed in the proper use of sex can keep his body and mind in proper health and can live a pleasant life throughout.

The practical principles of sexual health are not taught because the public regards the subject as unclean and indecent. Thus blinded, mankind presumes to clothe Nature in a veil because she seems to them impure, forgetting that she is always clean and that everything impure and improper lies in man's ideas, and not in Nature herself. It is clear therefore that man, not knowing the truth about the dangers of misuse of the sexual power, and being compelled to wrong practices by the nervous irritation resulting from unnatural living, suffers troublesome diseases in life and ultimately becomes a victim of premature death.
