The Northwest Branch of the Theosophical Society can be reached online at Thesosophy-nw.org.
The Theosophical Society itself is headquartered in Pasadena (California), and the site offers a wide host of materials dealing not only with theosophy but also with worldwide spiritual traditions and scientific theories as seen from a theosophical standpoint. These have titles such as “Hierarchies: The Structure of Nature” and “Teachers, Disciples and the Hierarchy of Compassion”. Inspirational writings are also featured, and the site includes a Collation of Theosophical Glossaries. A list amounting to more than 800 quality books that will be enjoyed by the younger ones is also part of the site, and it includes picture books and titles that deal with myths and tales. Resource books for adults are likewise detailed, alongside links for further sources for finding more children’s books.
