This thread is getting pretty catty so I hesitated to jump in, but Graham has peaked my interest by prescribing zen riddles. Since you chose to use it to defend your own knowledge of spirituality (whatever that is), please tell me what you think "the sound of one hand clapping" is, in one sentence or less. As such puzzles go it is short, sweet, thoroughly understood by the initiated, and yet it is surprisingly hard to find the answer on the intarwebs, so it may actually prove a valuable metric. If you don't know I wouldn't hold it against you, I am just curious.
Only initiates know? Sounds like applause to me.
The heart, body(soul), mind,spirit and void are all with ma ai.......break ma ai and you will hear the sound of one hand clapping.
