Snow can never emit flame.
Water can never issue fire.
A thorn bush can never produce a fig.
Just so, your heart can never be free
from oppressive thoughts, words, and actions
until it has purified itself internally.

Be eager to walk this path.
Watch your heart always.
Constantly say the prayer
“Lord Jesus Christ, have mercy on me.”
Be humble.
Set your soul in quietness.

The more the rain falls on the earth,
the softer it makes it;
similarly, Christ’s holy name
gladdens the earth of our heart
the more we call upon it.

— Hesychius of Sinai
