In Hebrew, the two sides of the Tree of Knowledge (Daath), written as Tob [טוב] and Ra [רע]. More accurately, טוב means "goodness" and רע means "impurity."

"In pure esotericism, good is all that is in its place; bad is all that is out of its place. Likewise, fire in the kitchen, when in its place, besides being useful, is good. Yet, the fire out of its place, burning the furniture of the living room, would be bad and harmful. Thus, any virtue, no matter how holy it might be, is good in its place; yet, it is bad and harmful out of its place. We can harm others with our virtues. Therefore, it is indispensable to place virtues in their corresponding place. What would you say about a priest who preaches the Word of the Lord inside a brothel? What would you say about a meek and tolerant male who blesses a gang of assailants attempting to rape his wife and daughters? What would you say about that type of tolerance taken to such an extreme? What would you say about the charitable attitude of a man who, instead of taking food home, shares his money among beggars who have a vice? What would be your opinion of a helpful man who in a given moment lends a dagger to a murderer? Remember, dear reader, that crime also hides within the rhythm of poetry. There is much virtue in the perverse one and as much evil in the virtuous one. Even though it may appear incredible, crime also hides in the very perfume of prayer." - Samael Aun Weor, Revolutionary Psychology
