Napoleon Hill called the thirteenth and final step of Think and Grow Rich, "The Sixth Sense," adding: "This principle is the apex of the philosophy."

Time has validated the success master's insight.

In The Sixth Sense,Mitch Horowitz, one of today's most literate voices of self-help, explores the practical uses of this culminating step in Hill's philosophy, including how:

Your brain is a "receiving station" sensitive to influences all around you. ESP, telepathy, and precognition are facts demonstrated by replicable and recent lab data. "Mental telepathy is a reality," Hill wrote, with emphasis in the original. He was right. Due to your receptivity to extra-physical impressions, you must carefully cultivate environment, relationships, and colleagues. Your psyche functions like any physical organ-it is subject to fatigue, exhaustion, and overuse, just as it performs better under conditions of health, vitality, and adequate rest. You must beware of factors that cloud your mind's functions, such as intoxication, boredom, poor physical habits, and negative emotions. Enthusiasm is a vital property in accessing imagination, intuition, and insight. By using all the lessons in Think and Grow Rich, it is possible to cultivate a sixth sense through which hunches and flashes of insight reach you. Pay attention to enthusiasms and forebodings. This may be the sixth sense communicating. You can trust intuitions and insights when they follow dedicated study and effort. These are not fickle or errant notions but possibly the subconscious and sixth sense breaking through. Precognition and retrocausality-the subject of recent academic studies and meta-analyses-demonstrate that future actions can improve current performance. An imaginary council, as described in Hill's final step, can augment-but not replace-the Master Mind principle. We experience daily moments that are "prime time" for intuition, autosuggestion, and ESP-related activity. Learn how to cultivate them.
