“The Ritual Magic Workbook: A Practical Course of Self-Initiation” by Dolores Ashcroft-Nowicki (ebook version)
"This is a carefully conceived course of instruction for anyone who wants to practice ceremonial magic, and has been written for students who are not part of a working group. Dolores Ashcroft-Nowicki takes the student, month-by-month, through a full year of magical training. She imparts her years of hard-earned experience in the clear, accessible, and often humorous style for which she is internationally known. Each month's work is concluded with practical exercises designed to give the student a sound working knowledge of ritual magic. Among the many topics covered are:
Constructing and consecrating a temple
Meditation and visualization techniques
Working in an elemental temple
Exploring the Inner World
Pathworking the Tree of Life"
