=Vitality determines results.=--Man has a three-fold nature; physical, mental and moral. In this life these natures are related and dependent. The sexual instinct has its seat in the physical nature, but in its functions it is closely related to the mental and moral. Whenever the sexual life is misdirected the mental and moral natures suffer. The sexual nature produces life--physical, mental and moral. It is by restraining this life force, this psychic force, this vital energy, within the body, and learning to direct it properly, that physical health and strength are attained and maintained; that intellectual vigor and brilliancy are realized; and that our emotional nature is developed in its expressions of tender feelings, purest love, truest sympathy, and passionate interest in the welfare of our fellow men. No one can have intellectual and moral development or enjoy a high degree of intellectual and spiritual life, if the sex function is abused. Parents with strong, healthy sexual natures parent the most perfect children. =Young married people should understand sexology.=--Thousands of young married people have never received any instruction from books, parents or doctors regarding correct sexual relations in the married life. Many of these have learned from sad experience that marriage does not mean unrestricted sexual liberty. Many who have sought the needed information from friends and books have been confused by conflicting opinions. The husband and wife who desire to be anything, physically, mentally or morally, must retain in their bodies as much as possible their sexual energy. In this is found the elasticity and strength of the muscles, versatility of the mind, strength and vigor of the constitution, which lend an indefinable charm to the masculine and feminine graces. All sorts of drugs and contrivances have been used by many married people to dodge the natural consequences of the sexual relations. Every attempt of this kind has resulted in some form of physical, mental or moral injury to those who have tried it, and it has strewn their pathway with a horde of physical weaklings and moral degenerates. All preventive and abortive methods, drugs and contrivances cannot be too severely condemned. Legitimate indulgence in the marital relation is allowable only when the act can be made a complete one; when, should conception occur, it would be a welcome result. An occasional union between husband and wife, if prompted by pure love, is not necessarily injurious or morally wrong. But when indulged in, it creates an unnatural desire and substitutes lust for love.
