Progression is a positive trait, as long as one keeps in touch with the past and has a staple backdrop to focus or fall back on. Although the Revised Expanded Third Edition contains all the wording and photographs that are reproduced in both the first edition, as well as this Revised and Expanded Second Edition, it comparatively represents a step into what was, for these latter two books, the future. The year 2019, in which I am writing this foreword, represents respectively 30 years and 20 years into the future since the publication of these two books, so I think this faithful reproduction of the Master Version by Q&I Publications is well timed. For some readers it might bring about nostalgia, for others it might be an eye-opener into a world that is not always truthfully represented, due to commercial or other reasons. For the teachers who I interviewed and have been embodied herein, I hope this Master Version will remain a testament into how they wished to be represented for time immemorial.
