Indra's Net, a metaphor for the non-dual nature of all

Interesting site discussing Indra's Net (or Indra's Web):

"The Net of Indra is a profound and subtle metaphor for the structure of reality. Imagine a vast net; at each crossing point there is a jewel; each jewel is perfectly clear and reflects all the other jewels in the net, the way two mirrors placed opposite each other will reflect an image ad infinitum. The jewel in this metaphor stands for an individual being, or an individual consciousness, or a cell or an atom. Every jewel is intimately connected with all other jewels in the universe, and a change in one jewel means a change, however slight, in every other jewel."
