B is for Breathe
Abbot Pastor said:
A man must breathe humility and the fear of God
just as ceaselessly as he inhales and exhales air.
from The Wisdom of the Desert (collected sayings of 4th century ascetics, compiled and translated by Thomas Merton)
A swimming picture because it’s in swimming that we learn to be intentional about our breathing until it becomes so natural that we no longer have to think about it.
