Here is the Brief Rule of St. Romuald, who founded the Camaldolese Order in Italy a little over a thousand years ago. The rule is taken from https://camaldolesedownunder.com/st-romualds-brief-rule/ this website of an Australian Camaldolese monestary:

Sit in your cell as in paradise;
put the whole world behind you and forget it;
like a skilled angler on the lookout for a catch, keep a careful eye on your thoughts.

The path you must follow is in the psalms – don’t leave it. If you’ve come with a novice’s enthusiasm and can’t accomplish everything you want, take every chance you can find to sing the psalms in your heart and to understand them in your head; if your mind wanders as you read, don’t give up but hurry back and try again.

Above all realize that you are in God’s presence, like a little chick tasting and eating nothing but what its mother brings.

Reflecting on this rule a year ago during the time of isolation imposed by covid19, I wrote the following:

This room has become the cell sustaining me,
with its bed and chair and desk,
its wallpaper looking just a bit like burlap,
a calendar that usually lags a month or two behind,
and stacks of unread books and magazines.
Art hung here and there tells me of the world
beyond these walls—a field in Idaho,
a lake spread like smooth flooring 
beneath clouds plastered softly to the sky,
a quaint European street,
and a room somewhere that’s always sunlit
even during these cloudy winter days.

Wanderlust reaches out of the frames to tug
at me, but I isolate in place,
fishing just among my thoughts,
freshened by the sunlight streaming
from the psalms that my heart sings.
I peck gratefully at whatever seeds
my mother-God supplies.
Contentment visits and
my cell expands to paradise.
