Forces of ignorance, of darkness.
The manipulation of the divine law to produce a series of ordered effects in time and space that manifest the separative goals of the magician.
The negative expression of the Seventh Ray is the use of Black Magic as the individual seeks to serve his own separated purposes and goals, or the use of Black Magic by the disciple of the Black Lodge for the purpose of opposition to the Divine Plan for humanity.
The consciousness imprisoned in the form created by the black magician is of his own separated identity. It is created by his personal desire and ambition, while the White Magician creates from the Soul level of the One Life, according to the Plan of that life.
The black magician is concerned with him or her self and their own rise to power or the accumulation of material gain. They care nothing for humanity.
