The poisons of attachment, aversion, and delusion produce an endless stream of negative behavior. The karma generated by this behavior is like an enshrouding blanket of negativity, making it impossible to see the truth of a given situation.
What was your thinking like the last time you felt anger, jealousy, envy, greed? What were you like when you were under their spell? You always ended up acting like some kind of demon. And afterwards, what did you feel? You felt shame, you felt guilt. And now you had to carry that around. Nothing is furthered by this kind of negative behavior.
The quality of love, all the higher angels of behavior, draws you into life with incredible force, and you see clearly. Your life becomes fantasy-free; you no longer live in some kind of fairy tale. You see the truth of things as they are.
