Magic is the second of the four Vidyas, and is the great mahaVidya in the Tantric writings. Black magic works with opposing poles. The white magician seeks the point of equilibrium or balance, and of synthesis. Black magic has for its symbol the inverted 5-pointed star. White magic uses the same symbol with the point uppermost.
Black magic is mahavidya without the light of atma-vidya.
White magic is mahavidya illumined by atma-vidya. Black magic is ruled over by the moon. White magic is ruled over by the sun. Black and white magic arose during the great schism which started during the fourth root-race. Black magic is based on the degradation of sex and of the creative function.
