"Our own globe earth, in fact is technically a "hell" because it is a relatively dense material sphere and the states of consciousness of the beings inhabiting it are relatively heavily involved in the webs of maya — illusion. For this reason H. P. Blavatsky in The Voice of the Silence speaks of "Men of Myalba" — Myalba being a Tibetan term used for one of the hells in the philosophy of Northern Buddhism, and Myalba is our earth. (Chapter 11)"
