THE four lectures printed in this volume were delivered to the delegates and members of the Theosophical Society, assembled for the Annual Convention at Adyar, Madras, on December 27th, 28th, 29th, 30th, 1893. They were intended to show the value of the teachings of H. P. Blavatsky as a guide to the obscurer meanings of the Hindu Sacred books, and so to vindicate at once the usefulness of the Theosophical and the Hindu doctrines.
