Every man is guided by two antagonistic forces of nature; one is higher divine force, which is always manifested in certain circumstances, influenced by particular spiritual books and other sources. Another force is lower self or the animal nature of man, leading to pervasion of mind. Self-control is the method to control this lower nature of man by manifesting higher powers latent in the spirit of every man. Having ascended the grades of evolution from the lower animals, man first lives on animal plane, his main objectives of life are purely animalistic and then he rises higher and higher till the latent powers in the spirit reveal itself and luminous in its own lights.
Self-control is essential for people who want to devote themselves in spiritual living. It is not manifested in people who vehemently obey the dictation of senses and blindly serves the internal masters of passion, anger, greed, self-delusion, pride and egotism. Those who can control themselves, check the mad rush of the mind toward sense objects, and who cease to obey those animal impulses, which are standing like huge walls in the path of spiritual progress, enjoy undisturbed peace as long as they live.
The attainment of self-control is easy for those who have learned to study their own minds. Studying their own minds, discovering weaknesses and strengths is helpful to reform own character. The natural tendency of human beings is to seek pleasure and avoid pain. As long as man lives in the darkness of ignorance and cannot trace the causes that make him happy or unhappy, as long as he does not understand whether happiness and pleasure come from external objects or from within, so he fails to be master of himself.
