 This was probably the reflection of some popular beliefs already widespread in Henan of the time.Han proclaimed the rebirth of Maitreya Buddha and the near coming of the "King of Light" (天下大亂，彌勒下生，明王出世).Apparently, he used the title for himself (although there is no such historical record, after his death his son became known under the title "King of Light the Young", which provides the indirect evidence.)
