Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Blavatsky's writings, including "The Secret Doctrine," explored esoteric spirituality, theosophy, and the synthesis of science, religion, and philosophy. She played a significant role in popularizing Eastern esoteric teachings in the West, influencing spiritual movements and philosophical thought.
