Eliphas Levi stated that the inverted pentagram was satanic:
"The Pentagram with two points in the ascendant represents Satan as the goat of the Sabbath; when one point is in the ascendant, it is the sign of the Saviour."
-Ritual of High Magic, ch. 5
- Eliphas Levi"A reversed pentagram, with two points projecting upwards, is a symbol of evil and attracts sinister forces because it overturns the proper order of things and demonstrates the triumph of matter over spirit. It is the goat of lust attacking the heavens with its horns, a sign execrated by initiates."
"The flaming star, which, when turned upside down, is the hierolgyphic [sic] sign of the goat of Black Magic, whose head may be drawn in the star, the two horns at the top, the ears to the right and left, the beard at the bottom. It is the sign of antagonism and fatality. It is the goat of lust attacking the heavens with its horns."
"Let us keep the figure of the Five-pointed Star always upright, with the topmost triangle pointing to heaven, for it is the seat of wisdom, and if the figure is reversed, perversion and evil will be the result."
What he said is correct, we don't approach the spiritual by means of the "earth pole"- "triumph of matter".
Rudolf Steiner on the pentagram:
"We're always surrounded by five ether streams in the world around us on earth. They're called earth, water, fire, air and thought ethers. These etheric streams are also active in man: earth ether from the head to the right foot, from there water ether to the left hand, from there fire ether to the right hand, from there air ether to the left foot, and then thought ether back to the head.
"This is the occultist's sacred pentagram, the symbol of man. Its point is directed upwards, which indicates that the spirit streams to man from the heights. The pentagram is present in many flowers and other things in nature. The sign of black magic is a pentagram with one point at the bottom, through which magicians attract bad forces from the earth and send them out of the two top horns into the environment by means of their bad will in order to use soul and nature forces for their own egotistical, evil purposes."This links in with another process used in Black Magic- drawing up forces through the feet.
Streams of ether are always circulating out of the cosmos through the human body. One such stream enters through the head, passes from there into the right foot, then into the left hand, then into the right hand, then into the left foot, and from there back to the head. If we think of a man standing in the position just described, with outstretched arms, then the streaming has the form of a pentagram.-Guidance in Esoteric Training, Talks & writings 1903-1913, GA#245
It would be bad for man if the stream did not enter into him through the head but through the feet. All evil influences enter the human body through the feet. The black magicians make use of this.
