Published in 1897, Ancient Wisdom is Annie Besant's elementary review of the general principles and truths that are the foundations of theosophical teachings. She shows how the sevenfold nature of the human individual—both the higher cerebral aspects and lower bodily ones—fit in with the cosmos and concepts such as karma and reincarnation. Chapters concern the relationship of the Physical to the Mental as well as the Astral, Kamaloka, Devachan, and the Buddhic and Nirvanic planes.
