The Theosophical Society is composed of students belonging to any religion in the world or to none, who are united by their approval of the Society's Objects. Their bond of union is not the profession of a common belief, but a common search and aspiration for Truth in an environment of freedom of thought. The Society welcomes as members those who are in sympathy with its Objects and who are willing to abide by its Rules.
Requirements
It is recommended that individuals interested in applying to join the Society attend a few meetings in order to get to know a local Lodge or Group, and/or acquaint themselves with some of the literature produced by the Society. Application for membership of the Society can be made through a Lodge or group of your country. Some Sections require two sponsors for membership applications. The following link will show Theosophical Societies in countries.
