_The Will_.--A firm determination must be formed to lead a life of purity; to quickly quench the first suggestions of impurity; to harbor no unchaste desire; to purge the mind of carnal thoughts; in short, to cleave fast to mental continence. Each triumph over vicious thoughts will strengthen virtue; each victory won will make the next the easier. So strong a habit of continence may be formed that this alone will be a bulwark against vice. _Diet_.--He who would keep in subjection his animal nature must carefully guard the portal to his stomach. The blood is made of what is eaten. Irritating food will produce irritating blood. Stimulating foods or drinks will surely produce a corresponding quality of blood. Irritating, stimulating blood will irritate and stimulate the nervous system, and especially the delicate nerves of the reproductive system, as previously explained. Only the most simple and wholesome food should be eaten, and that only in such moderate quantities as are required to replenish the tissues. The custom of making the food pungent and stimulating with condiments is the great, almost the sole, cause of gluttony. It is one of the greatest hindrances to virtue. Indeed, it may with truth be said that the devices of modern cookery are most powerful allies of unchastity and licentiousness. This subject is particularly deserving of careful, candid, and studious attention, and only needs such investigation to demonstrate its soundness. _Exercise_.--Next to diet as an aid to continence, perhaps of equal importance with it, is exercise, both physical and mental. It is a trite proverb, the truth of which every one acknowledges, that "Satan finds some mischief still for idle hands to do," and it is equally true that he always has an evil thought in readiness--speaking figuratively--to instill into an unoccupied mind. A person who desires to be pure and continent in body and mind must flee idleness as he would the devil himself; for the latter is always ready to improve upon the advantages afforded by an idle moment, an hour given to reverie. We have the strongest testimony from the most eminent physicians in regard to the efficacy of exercise in overcoming abnormal sexual desires. Mr. Acton relates the following statement made to him by a gentleman who has become distinguished in his profession:-- "'You may be surprised, Mr. Acton,' said he, 'by the statement I am about to make to you, that before my marriage I lived a perfectly continent life. During my university career, my passions were very strong, sometimes almost uncontrollable, but I have the satisfaction to think that I mastered them; it was, however, by great efforts. I obliged myself to take violent physical exertion; I was the best oar of my year, and when I felt particularly strong sexual desire, I sallied out to take my exercise. I was victorious always, and I never committed fornication. You see in what vigorous health I am; it was exercise alone that saved me.'"
