Truly happy people fear nothing. Ego makes people unhappy, so they try to become happy, channeling their energy in the wrong direction. People learn to fear (pain, punishment, etc.). Then ego makes people happy enough to become attached, to desire things (that will make them happier or less unhappy). Most people channel their energy toward the solidification of their prison. Even thinking of channeling their energy somewhere else is sacrilege. If the energy of the soul is properly channeled, people are happy and free.
