It is a well known fact that we can produce any effect desired when we understand causes, and can master those causes. And as the process of thinking is the one underlying cause in the life of man we naturally become master over all life when we can understand and master the process of thinking. Each 'process of thinking produces its own results in mind and body and acts indirectly upon all the actions and efforts of mind and body. Therefore, through adverse thinking al most any undesirable condition may beproduced while almost any condition of worth and value can be produced through wholesome thinking. Certain. Processes of thought will lead to sickness, others to poverty, while processes of thought that are entirely different from these will lead to health, power and prosperity. Through chaotic thinking one can bring about years of trouble and misfortune, while through a properly arranged sys tem of thinking one can determine his own future for years and years in ad vance. Everything that happens to a man is the result of something that he has done or fails to do., But since both actions and inactions come from corresponding states of mind he can make almost any thing happen that he likes when he learns to regulate his thinking. This may seem to be a very strong statement, but the more perfectly we understand the rela tion of mental action to physical and per sonal action the more convinced we become that this statement is absolutely true. When we study the laws of nature we find that certain results invariably followcertain uses of those laws; and that other results follow the misuse of those laws. We find that a misused law can finally carry you to the lowest depths, and that a law that is perfectly understood and properly applied can carry you to the greatest heights. In the use of natural law, however, we are at liberty to change our mind at any time; that is, when we find ourselves going down we can turn about and go the other way; though the fact remains that if we continue the down grade we will finally reach the low est depths. The same is true when we find ourselves advancing; we may be come negligent and fall back, but the law in question can carry us on higher and higher without end if we choose to go. The laws that govern thinking are just as absolute as the well known laws of nature and will serve man just as faith fully after he has begun to apply them with understanding.
