The gross receipts herein reported are from the sale of theosophical and religious books and articles as well as donations. These donations have also furnished the capital for a modest investment account. The theosophical archives contains around 35,000 books on religion, philosophy and science as well as many other topics and continues to be added to. The sale and distribution of theosophical books and articles contributes directly to the exempt purpose of the theosophical endowment corporation and its parent organization, the theosophical society, as that purpose is set forth in the articles of incorporation.
