The journey, like the crossing of the great halls in the Egyptian underworld, therefore signifies the overcoming of a psychic obstacle, or of an autonomous complex, suitably represented by a planetary god or demon. Anyone who has passed through all the spheres if free from compulsion: he has won the crown of victory and become like a god.” The journey is an initiation, or a series of initiations, taking place in the imaginal world. The music that is heard there is none other than the knowledge gained in these initiations by those who have attained the requisite stage of psychic growth.
The Tritone (Devil's Note) :Diabolus en Musica
Three whole tones (the Tritone) is six semi-tones, and six is another number that has become associated with the mysterious figure of the Devil through the number 666, which is actually the divine number of the Sun and the occult number of the Hexagram, which is a magickal symbol of the Sun.
The Tritone is made up of three whole tones, thus it was originally associated by the Church with the Holy Trinity and when this did not work it was linked to the Devil, who was also connected with the number three by the Church (let us not forget the Unholy Trinity and the number of the Devil, which is made of three sixes.
Qabalistically speaking, the Devil is linked to the third Sephira on the Tree of Life of the Qabalah called Binah (Understanding) through its connection to the gods Pan, Set and Saturn (Satan), who are forms of the Devil.
Binah is the Sephira of Saturn on the Tree of Life in the Qabalah, and the Tritone itself became associated with the planet Saturn in medieval times, since Saturn was thought to be the planet of the Devil.
The Tritone adds a spiritual tension and mysterious quality of sound which cannot be had otherwise. Like the Devil, who represents one half of the nature of man, the ambiguous Tritone is one half of the Octave, it pivots and divides the Scale into two equal parts, and it is the same as its inverse.
