Tisziji takes a closer look at the spiritual implications of misdirected Mastership in his book, Once Is for Always, while recognizing the essential function of all True Masters, but also the confusion that has resulted from the many teachings which have been shared in different styles through different teachers, at different points in time. Tisziji has taught that many traditional and even New Age spiritual works have become massive and powerful organizations which conscript seekers and offer institutionalized religious instruction, disregarding the true needs of the individual.
