Qlippoth

"The titles of the Qliphoth, generally speaking, suggest the vice characteristic of the Sephira or other idea to which they are attributed. Thus the Thaumiel refer to Kether, because their characteristic is to possess two contending heads, and so to deny the unity of Kether. So also the Golachab are giants like volcanoes, symbolizing energy and fire, and their liability to appear as tyranny and aimless destruction. Similarly, the Qliphoth of Venus are carrion birds, as opposed to the dove, sparrow, etc."

"In a previous chapter we have referred to the Qliphoth, the evil and averse Sephiroth; the time has now come to study them in detail, even though "these are awful forms, dangerous even to think upon." ... The Qliphoth are aptly termed the evil and averse Sephiroth, for they are not independent principles or factors in the cosmic scheme, but the unbalanced and destructive aspect of the Holy Stations themselves. There are, in fact, not two Trees, but one Tree, a Qliphah being the reverse of a coin of which the obverse is a Sephirah."
