Madam Blavatsky - Dawn of a New Age Religion
Resource: Mind Map
Here is a mind map of Madam Blavatsky and just some of the connections she has. She has been a huge influence in the creation of the New Age Religious Movement and its infiltration into Christian teachings.
The web for this is much bigger than I have expressed here. However, this should help you on your way to researching this particular topic and the influence it has had on the sociological and political landscape.
If and when I do more mind maps in the future, this will tie into them in some way or another.
She was a huge influence on the modern spiritualist movement at the turn of the century. I believe they still use her books in Spiritualist churches.
