Imagine a bubble arising from the ocean. Now imagine a small bubble forming within the larger bubble, both floating above the water.
The small bubble begins to examine its world. It becomes a master of the nature of the larger bubble, knowing all there is to know.
The small bubble bursts, becoming one with the large bubble, realizing all knowledge was no knowledge, a mere creation within himself.
The large bubble bursts, merging back to the ocean. No knowledge, no realization, no other, just ocean.
All knowledge is false. All unknowing is Truth.
