This work is designed to give the reader a bird's eye view of the salient features in Jewish mysticism rather than a solid presentation of the subject as a whole. Should the reader be stimulated into a deeper study of the subject, the bibliography at the end of the book will lead the reader to the missing parts. Contents: some early elements, Essenism; Merkabah (chariot) mysticism; Philo, metatron, wisdom; kingdom of heaven, fellowship, Shechinah; book of Yetsirah; some general features of the Zohar mysticism; ten Sefirot; the soul.
