Raghavan Iyer founded HERMES, a journal of Theosophical Wisdom, just prior to the beginning of the 1975 Cycle in Santa Barbara, California, as one of several vehicles for the current behind the 7th Century Impulsion. In that journal, he illustrated the ways in which Mahatmas have worked and continue to work in the world. In the article, "The Seventh Impulsion: 1963-2000", he made clear that the Mahatmic impulsions were concentrated in the last quarter of each century, but that preparations for them occurred earlier, and that their reverberations lasted far beyond the conclusion of each quarter-century cycle in an unfailing continuous stream. Near the beginning of 1976, after a year of guiding the golden HERMES current, Professor Iyer determined that those thinkers and teachers most involved in the Seven Century Plan should be honored through writings - called the Teacher Articles - that described the hidden current behind their lives and the timeless context for their work within the cycles of time. All of the Teacher Articles were written from a Theosophical perspective based, in large part, upon the philosophy expounded in H. P. Blavatsky's The Secret Doctrine. This collection of essays contains those articles that first appeared in HERMES as an exploration of the Seven Century Plan.
