Parasitic existence, as an aside, is defined as the actual existence of things that are not real things. Holes, darkness, shortages, incorrectness, and evil are not matter, energy, or spirit, yet as a shadow can kill plants that need sun, or a lack of food can kill a person, shadows and lack of food have actual existence without being real things.
Uwepo wa kimelea, kama kitu cha ndani, unfafanuliwa kuwa ni uwepo halisi wa vitu ambavyo si vitu halisi. Mashimo, giza, upungufu, kutokuwa sahihi, na maovu si mada, nishati, au roho, lakini kama ambavyo kivuli kinaweza kuua mimea ambayo inahitaji jua, au upungufu ea chakula unavyoweza kuua mtu, vivuli na upungufu wa chakula vina uwepo halisi licha ya kutokuwa vitu halisi.
