Do the Naths use Golden Dawn style banishings and rituals in their practice?
No. The Nath tradition is ancient and complete in itself. The use of modern magical rituals involving Judeo-Christian angels and names of God plays no part in the practices of the Naths. Of course, individual Naths may have also studied or practiced western magick before becoming Naths. These individuals are in no way prohibited from continuing to use practices from other traditions, but this in no way makes these practices part of or necessary to the Nath tradition.
