Sometimes silent sitting resembles what could be imagined as death.
It is not death. Nor is death an imagined thing. Silent sitting is only silent sitting. Imagination is something else. It happens of itself. As does, I suspect, death. In the presence of imagination, silence, or death, I am astonished. That I am, or you are, or this is. Astonished!
Wittgenstein said that with death, the world does not alter, but comes to an end. He said that death is not an event in life, that we do not live to experience death.
"There are, indeed, things that cannot be put into words. They make themselves manifest. They are what is mystical." (Proposition 6.522, from Tractatus Logico-Philosophicus, by Ludwig Wittgenstein)
Mystical: 1 a: having a spiritual meaning or reality that is neither apparent to the senses nor obvious to the intelligence mystical food of the sacrament> b: involving or having the nature of an individual's direct subjective communion with God or ultimate reality mystical experience of the Inner Light>
(-Merriam-Webster)
Each day we pray for those who are dying, those who will die today, and all those who have died, especially those with no one to pray for or remember them. Then we say the Our Father, asking that what is "as it is" in heaven will be "as it is" also on earth.
When truly sought even the seeker cannot be found.
Thereupon the goal of the seeking is attained,
And the end of the search.
At this point there is nothing more to be sought,
And no need to seek anything.
- Padmasambhava, (Daily Zen)

What are we looking for? Kids on corners looking out for police. Lobbyists looking left and right with their money. Soldier behind automatic weapon acutely aware of every movement. Women and men at red lights taking the only pause of their crowded day. Monk in solitude gazing at nothing.
Which One
I eye the driver of the Chevrolet
pulsing beside me at a traffic light
the chrome-haired woman in the checkout line
chatting up the acned clerk
the clot of kids smoking on the sly
in the Mile-Hi Pizza parking lot
the meter reader, the roofer at work
next door, a senior citizen
stabbing the sidewalk with his three-pronged cane.
Which one of you discarded in a bag
—sealed with duct tape—in the middle of the road
three puppies four or five weeks old
who flung two kittens from a moving car
at midnight into a snowbank where
the person trailing you observed the leg
and tail of the calico one that lived
and if not you, someone flossing her teeth
or watering his lawn across the street.
I look for you wherever I go.
(Poem: "Which One" by Maxine Kumin, from Jack and Other New Poems. W.W. Norton, 2006. The Writer's Almanac)
I like the old phrase: "I'm looking out for you." Someone watching out for us is a useful ambiguity. Will we be found? Will I be protected? Do we thank someone? Or worry they're closing in on us?
The boy looks out from a mountain in Austria. The dog, from a mountain overlooking Penobscot Bay. The gentleman in the photo looks from a rise over reservoir in Granville. Of the three, only the boy remains manifest.
Before going to bed, brief silent sitting in front room. A foot of snow, and still falling.
It's right here, at hand, under foot.
No need to seek anything.
