"In a dream, we enjoy ourselves although there is nothing enjoyable there; we are irritated although there is nothing irritating there; we are frightened although there is nothing to be afraid of there. In the same way, beings of the threefold world, in the sleep of ignorance, are irritated although there is nothing irritating, enjoy themselves although there is nothing enjoyable, and frightened although there is nothing to be afraid of."

~ Nagarjuna – Mahaprajñaparamitopadesa
