Although I have not yet fully completed this book, I have to say this has to be one of the greatest books ever written! "How to know higher worlds" has drastically changed the way I consider myself and the world around me. This book is a must have for those searching to enrich their inner (and somewhat outer) lives. Steiner introduces many basic esoteric priciples and clears up a lot of the stigma revolving around modern occultism. This book is a fantastic basis for the beggining occultist to take their first steps into the spiritual world. Most of the books content involves conditioning of the spiritual senses and occult philosophies. So, if you are seriously considering awakening yourself to the spiritual world, Steiner is a fantastic stepping stone and this book is a definite must have.
