Did Buddha come to Teach the Law of One?

[Cainite]

They pay respects and praise some higher entities in rituals and mantras.

They believe in lower and higher beings. devas, hungry ghosts, ...

I’ve been thinking more and more lately that dogs are hungry ghosts right now

Hungry ghosts constantly seek to quench their unquenchable thirst. some humans do resemble them. not dogs though.

Q'uo has commented about the Buddha on a few occasions, along with most of the other major philosophical/spiritual figures in history.  The best discussion I could dig up is here, with Q'uo contrasting the teachings of Jesus and the Buddha.  The TL;DR is that, in Q'uo's view, neither was teaching the LOO specifically.  Rather, Jesus was teaching Love and Buddha was teaching Wisdom - both useful in their own ways for those seeking awakening or reunification.

Yeah, but why would buddha teach wisdom when mankind hadn't learned unconditional love yet? this has always confused me.
Sufism focuses on both.
