Strange and mysterious name to give to the Spirit of Darkness. Freemasons teach that Satan and Lucifer are not the same being. Now, you are deceived no longer.

A mirrored chamber provides greater confrontation for the celebrant, making him hyperconscious of his role.

An austere chair is provided in which the celebrant sits during the first part of the ritual. The coffin may be of any type, although a traditional hexagonal style is recommended, as this is the type depicted in the actual sigil of the Sixth degree of the Templars and, combined with the skull and crossbones, is retained in Masonic symbology. The coffin must be large enough to accomodate two persons, hence special construction or modification is likely to be necessary. The usual devices of Satanic ritual are all employed. Albert Pike teaches that Freemasons of the 30-32 Degrees are to be told that Lucifer is the one whom they serve.
