Janis Lander has written a handy reference to assist people with meditation practices, including guidelines for assessing teachers, tips for dealing with common problems, and a context for unsettling experiences. The narrow focus of spiritual systems is defined as knowledge acquired within a theoretical framework of energy structures and consciousness. Lander explores standard methods and predictable outcomes in both Western and Eastern spiritual systems, seeking a common thread and a broad vision. Spiritual art is examined as an iconography for philosophical concepts. The book is based on twenty-five years of practice and teaching, and Dr Lander has previously published her research with Routledge/Taylor & Francis. The author is presenting ancient knowledge reconsidered in light of 21st century science and technology.
