The Master Game by Robert de Ropp is a self-help book exploring higher states of consciousness.

The book uses the metaphor of games to describe different levels of human experience, from low, destructive games to the ultimate "Master Game" of self-realization. De Ropp synthesizes various methods, including autogenic training and the prayer of the heart, to achieve this higher consciousness. The text also discusses the importance of self-observation, physical and mental disciplines, and the role of community in spiritual growth.

Finally, the book touches upon the dangers of misusing drugs to achieve spiritual experiences.
