Including a biographical annotation on the life and achievements of St. Augustine. *** The importance of the letters of eminent men, as illustrations of their life, character, and times, is too well understood to need remark. This is especially true of the Letters of Augustin. A large number of them are ecclesiastical and theological, and would in our day have appeared as pamphlets, or would have been delivered as lectures. There are none of his writings which do not receive some supplementary light from his letters. The subjects of his more elaborate writings are here handled in an easier manner, and their sources, motives, and origin are disclosed. This edition contains his complete letters as well as more than 1500 illustrating endnotes. *** Echoes of the Eternal is a monumental series that brings together the defining texts of the world's spiritual, religious, and mythic heritage. From the sacred scriptures of Christianity, Islam, Buddhism, Hinduism, Judaism, and other global faiths, to the mystical writings of saints and sages, the myths of ancient civilizations, and the arcane literature of secret societies and occult traditions-this collection explores the full spectrum of humanity's search for the divine, the mysterious, and the transcendent. Each volume shapes spiritual consciousness and cultural identity across time. Whether it is the poetic wisdom of the Bhagavad Gita, the visionary revelations of the Qur'an, the esoteric allegories of the Kabbalah, the shamanic myths of indigenous peoples, or the secret doctrines of the Rosicrucians and Freemasons, this series reveals how humans have long sought to explain existence, destiny, and the unseen forces of the cosmos.
