Just a recommendation; if Madame Blavatsky's works are of interest to you; I'd recommend looking in depth & reading the works of and/or about Aleister Crowley, Golden Dawn , Spiritualism (as a Religion) & Thelema.
Sacred Texts is a very informative website that contains a plethora of reading materials on the topics mentioned above, as well as, Ancient Religions & Philosophies, Esotericism, Magick, Occult, etc.
