Here's some delicious mind candy for you. Is the Universe a Hologram?
Hua-Yen Buddhism teaches much the same; the whole contained in the parts and so forth. Not that I really know what I'm talking about concerning Hua-Yen, but I just happened to read the above piece immediately after reading a piece about Hua-Yen Buddhism in Buddhadhamma Magazine. Coincidence? Is that even a meaningful concept?
One detail from the Buddhadhamma piece; one Hua-Yen master built a shrine room with all six sides mirrored and a Buddha image suspended dead-centre. Damn, I want one of those!
