Well, I think the facts would argue otherwise. The ancient Greek Tradition of theo-sophia, for example, claims its Source as the Divine Itself, which in their own words is 'beyond-being'.The Source of Divine Wisdom or Theosophy is - surprise - Divine Beings. Call them buddhas or avatars.
Beings of light are not the source of the light that is their being.
All being in its ground is lit by the same light, no matter how luminous or obscure or occluded that light may be.
