This book addresses all who seek to know life’s profound spiritual reality. The book is exactly what its title says: an urgent call to wake up to how we delude ourselves by interpreting physically what is not physical but spiritual. The book identifies many of our most typical illusions so that we can reflect on them. It urges us to wake up to how we neglect our real inner work of self-transformation but settle instead with concepts and conventions. Urging us to go beyond concepts and illusions, the book explains in simple and clear terms why we can so easily misunderstand the master’s teachings.
