Boredom has been used as a technique, it is a device. In Zen, boredom is used as a device: you are bored to death, and you are not allowed to escape. You are not to go outside, you are not to entertain yourself, you are not to do, you are not to talk, you are not to read novels and detective stories. No thrill. No possibility to escape anywhere.
It seems to me that all of the evil in life comes from idleness, boredom, and psychic emptiness, but all of that is inevitable when you become accustomed to living at others' expense.
The beauty of facing life unprepared is tremendous. Then life has a newness, a youth; then life has a flow and freshness. Then life has so many surprises. And when life has so many surprises, boredom never settles in you.
Of course boredom may lead you to anything. It is boredom sets one sticking golden pins into people, but all that would not matter. What is bad (this is my comment again) is that I dare say people will be thankful for the gold pins then.
I wish to speak with all respect of persons, but sometimes I must pinch myself to keep awake, and preserve the due decorum. They melt so fast into each other, that they are like grass and trees, and it needs an effort to treat them as individuals.
