我告訴你他們告訴我 你可以用你所有的鑰匙去試試……. 」
參與者身上的鑰匙絕大部份是不能開鎖的(第一次被騙) ，即使鑰能被打開他也會撞牆(第二次被騙) 。 那堆無用的鑰匙已經說明了一切。既然無門可通，人就是用其他的辦法像是：梯子所象徵的修行、黑布所象徵的冥想一類的心靈活動來救濟，結果也都將失敗。
Door to Eternal Happiness
2.15-2.21,1986 Sunny Art Gallery
By the entry there was a heap of envelopes with printings on the cover：
“ I tell you what they said: A world of eternal happiness is behind the door.
I tell you what they said: This door is the only access for entry.
I tell you what they said: The key is the only tool to unlock.
I tell you what they said: If you have the key that unlock the door then you own this world.
I tell you what they said: You may try all your keys………… “
Participants were asked to try all their keys and then open the envelope with lines printed as follows:
“ I tell you the truth: One can be cheated only once if the key does not unlock the door.
I tell you the truth: If the key does work then you are twice cheated. “
If one fail to open the door with his keys，he is cheated the first time .If one can open the door, he would face the wall and still find no way out of it. So, he is cheated the second time. The heap of discarded keys is self-explanatory. Since this door is a nihility, all the efforts such as the practice of moral teachings (symbolized by the ladder); or spiritual activities of meditation (symbolized by the black strap) should end in futileness.“
