0Alice A. Bailey is one of the most noteworthy figures of early 20th century Theosophy. Mostly known for her "revealed" works, she also penned several books and compilations of lectures; this being one of them, namely on the subject of the atom, its spiritual significance, and attendant subjects.Some of the claims it makes are actually accepted today (such as the energetic form of the atom, in the basic sense) while some of its material (the human as a central radiation point) is largely considered to be pseudoscientific. A fascinating look at early 1920s scientific thought as well as religion.
