On praying for one another

"But he was not reluctant,
when he discerned the time was right,
to involve himself in the affairs of his neighbors,
and attend to their salvation.
For his safest haven was prayer;
not prayer of a fleeting moment, empty and proud,
but prayer that was prolonged,
full of devotion, peaceful in humility.
If he began at night,
he was barely finished in the morning.
Walking, sitting, eating, drinking,
he was focused on prayer."
