Bill Heidrick gives his own interpretation on the adverse tree, saying that the spellings are "mostly reconstructions with alternatives. Nonetheless, it is believed that the majority of the above are at least suitable if not perfect". He also goes on to say that "These names are sometimes called the 'adverse Sephiroth' instead of the Demonic Orders. A. E. Waite makes this later point in his Holy Kabbalah, page 256."
