I recently received a quote from the book The Magnetic North by Sarah Wheeler that contains a moving encouragement to sit lightly to worry-mind.
In her book Wheeler quotes Alexander Solzhenitsyn. She sets up the quote saying,
In the first volume of The Gulag Archipelago, the author describes being transferred under armed guard from one prison camp to another.  On the journey, made on public transport, Solzhenitsyn overhears the chattering complaining of free men and women.  How can it be of any interest, the fettered prisoner wonders, in the face of the barbarity to which he has been condemned, that a woman squabbles with her daughter-in-law?  ‘Do not pursue what is illusory’. 
Solzhenitsyn goes on to encourage his read to take to heart the transient nature of,
property and position: all that is gained at the expense of your nerves decade after decade, and is confiscated in one fell night.  Live with a steady superiority over life — don’t be afraid of misfortune, and do not yearn after happiness; it is, after all, all the same: the bitter doesn’t last forever, and the sweet never fills the cup to overflowing.  It is enough if you don’t freeze in the cold, and if thirst and hunger don’t claw at your insides. If your back isn’t broken, if your feet can walk, if both arms can bend, if both eyes see, and if both ears hear, then whom should you envy?  And why?  Our envy of others devours us most of all.  Rub your eyes and purify your heart — and prize above all else in the world those who love you and who wish you well’ 
Fewer things are quite as important as worry-mind would have me believe. Those things about which I fret are in the end all transient and ephemeral.
The Psalmists says,
4 ‘Lord, let me know my end,
and what is the measure of my days;
let me know how fleeting my life is.
5 You have made my days a few handbreadths,
and my lifetime is as nothing in your sight.
Surely everyone stands as a mere breath.6   Surely everyone goes about like a shadow. (Psalm 39:4-6a)
But the ancient poet does not stop there. He goes on to affirm
Surely for nothing they are in turmoil;
they heap up, and do not know who will gather.7
‘And now, O Lord, what do I wait for?
My hope is in you. (Psalm 39:6b, 7)

The Psalmist found “hope” when he stopped for a second and asked a simple question – “what do I wait for?” What do I really want in life? What do I really believe most deeply about the reality of my being as a creature created in God’s image?

I put a stick in the spokes of the spinning whir of worry-mind when I stop for a second and ask myself the simple question – “Is this true?”

Is it actually true that if…. happens, my life will be utterly destroyed? Is it true that if I drop this ball, my credibility will be completely undermined and no one will ever again take me seriously? Or, even better, if I am completely undermined and no one takes me seriously, will my life come to an end? Is it true that my well-being is controlled by how things are going in “my life” or by how you respond to me? Is it true that if I lose this person, relationship, thing in my life, that I will be plunged into a meaningless dark abyss of nothingness?

The other question that is helpful in dealing with worry-mind is – “What is really going on here?” When my thinking mind starts to spin out of control, I need to ask myself what it is that I am really afraid of. Unless I am standing in the middle of the road with a large truck hurtling down upon me, I will generally find that most of the things of which I feel fearful are simply fantasies of the mind. When I look into them and ask “What is really going on here?” they begin to dissipate.

Questions open a small space in my being. This small space is the place the Psalmist found “hope”. Opening space where I can reconnect with my awareness of that LIFE which never dies, is the key to the end of worry-mind.

Opening space takes practice which is why twice a day for twenty minutes, I sit in silent prayer intentionally opening space and allowing all those things to which worry-mind is so attached, drop away. This is the place where the silent presence of God awaits and I find the reality of LIFE reaffirmed and strengthened.
