Power of the Mind by Swami Sivananda

Mind is the greatest force on this earth. He who has controlled his mind is full of powers. He can bring all minds under his influence. All diseases can be cured by psychic healing. One is struck with awe and wonder at the marvels and mysterious powers of the mind of Man. The source or home or support for this mysterious mind is God. Every human being has, within himself, various potential capacities. He is a magazine of power and knowledge. As he evolves, he unfolds new powers, new faculties and new qualities. Now, he can change his environments. He can influence others. He can subdue other minds. He can heal others. He can get plenty of material things. He can conquer internal and external nature. He can enter into the superconscious state.
