"One of these apprentices was Helena Petrovna Blavatsky—a great soul who was sent out to offer knowledge to the world. With Colonel Henry Steel Olcott she founded The Theosophical Society for the spread of this knowledge which she had to give. Among those who came into contact with her... Mr. A.P. Sinnett... his keen intellect at once grasped the magnitude and the importance of the teaching...
