It is a law of human biology that the direction of this energy is very largely under the direction of the mind. If one desires bodily development and will take regular and systematic physical training, this energy can be built into the muscles giving them the body of an athlete. If one desires intellectual development and will regularly and systematically exercise every faculty of the mind, this energy will be directed to the brain, resulting in intellectual brilliancy. The same law applies with equal force to the development of the feelings, sentiments and emotions of the moral nature. If we take normal physical, mental and moral exercise, this energy will be conserved in the blood, which is the life, and directed so as to produce a perfect development. Sin alone has brought conflict and inharmony into our three-fold nature and prevents perfect happiness and perfect development. This is an appalling fact. We are hereditarily degenerate. God’s grace and the right exercise of the will in relation to perfect self-control are necessary conditions of individual and race improvement. If lascivious thoughts are allowed control of the will, this creative life will be misdirected, the generative system will become abnormal, resulting in sexual weakness and depriving the entire being of the benefits of this energy. =The relation of reading to the disposition of the sex life.=--A fondness for reading highly romantic, intensely sensational, untrue and immoral novels is abnormal and lead to a misdirection of this creative life. There is the romantic element in our nature which should be developed, but it should not be over-developed. We should have a balanced development. The degenerate elements in our nature, inherited or acquired, should be suppressed and eliminated. The vicious novel increases the creation of the sex life and at the same time misdirects it. This intensifies our degeneracy. Reading good literature, facts or fiction, or both, is normal and leads to a natural generation of and distribution of this energy. Girls should read a general line of good literature. The romantic nature is especially active in youth. It is for this reason that the youth is inclined to read only fiction. If in young life we would develop properly, we should choose a general line of reading, embracing some of the standard books of fiction, history, travel, poetry, biography, essays and religion.
