Reincarnation of a person in someone's thought while awake, or in his dream while asleep, can be recognized; for all beings besides his own self produced in such a way, are produced out of his own mind; therefore they may be called reincarnations. Yet this would not be perfectly justified, because every thought and dream has a birth, life, and death. So even they can be taken as individualities, and as a world produced from a single being.
