A word used often in anthroposophical literature to describe spiritual influences. Luciferic beings have plagued humanity along with the destructive ahrimanic beings. They are spirits that should have dealt with the eternal alone but have strayed into the realm of time.
Luciferic beings influence us to return to our own interests which
may avoid a wretched philistinism but also influence us to
loose interest in others. They present a personal
soul nature of wisdom and temptation.
It is only because of luciferic beings that we do not pursue incessant
knowledge of everybody in our enviroment.
In the case of "genuis," luciferic beings
may latch on to an embryo for their own immortality.
