The provided text, "AUTO-SUGGESTION: THE MEDIUM FOR INFLUENCING THE SUBCONSCIOUS MIND," from Napoleon Hill's Think and Grow Rich, outlines auto-suggestion as the method for influencing the subconscious mind. It asserts that thoughts, especially when mixed with emotion and faith, can voluntarily penetrate the subconscious and drive actions. The excerpt instructs the reader to repeatedly affirm their desires, particularly financial goals, with strong feeling and belief, thereby creating thought habits conducive to achieving them. This process, requiring persistence and concentration, is presented as the key to mastering one's destiny by controlling the subconscious mind and accessing "Infinite Intelligence" to devise plans for success.
