From Theosophical University Press
For several centuries prior to the founding of The Theosophical Society in 1875, individual "theosophers" in Britain and Europe were quietly in touch with one another — all seekers of the "inward way."
Theosophic Correspondence (1792-1797) is a series of inspiring letters, personal and philosophic, exchanged during the climactic days of the French Revolution between Kirchberger, member of the Sovereign Council at Berne, Switzerland, and Saint-Martin, whom Kirchberger regarded as "the most eminent writer . . . and most profound of his age."
