The new spiritual 'supermarket' of today brings both perils and opportunities. This book is the result of a major and lengthy study conducted at the Centre for Study of New Religious Movements (California) on the topic of spiritual tyranny versus legitimate spiritual authority, including articles and interviews from many luminaries of inner transformations. It will sharpen the seeker's ability to recognise valid approaches to inner spiritual development and provides enabling to choose a suitable spiritual path and group with discrimination.
