" But what is passion, what are emotions? There is the source of fire, there is the fullness of energy. A man who is not on fire is nothing: he is ridiculous, he is two-dimensional. He must be on fire even if he does make a fool of himself. A flame must burn somewhere, otherwise no light shines; there is no warmth, nothing. "

― C.G. Jung , The Psychology of Kundalini Yoga: Notes of the Seminar Given in 1932
