Guard your heart

Some notes I’ve jotted down in the past few days. They seem related.

“If someone has repented once of a sin, and again does the same sin, this is a sign that he has not been cleansed of the causes of the sin, wherefrom, as from a root, the shoots spring forth again.”
— St. Basil the Great

“Until you have eradicated evil, do not obey your heart; for it will seek more of what it already contains within itself.”
— St. Mark the Ascetic, in “On the Spiritual Law: Two Hundred Texts”

“Keep your heart with all vigilance; for from it flow the springs of life.”
— Proverbs 4:23

“Train yourself to cut off an intrusive thought immediately… be at pains over this, so that you acquire the habit. The soul is a creature of habit: according to the habit you have acquired, so will you act.”
— Saint Silouan the Athonite

“People do not decide their futures, they decide their habits and their habits decide their futures.”
― F. M. Alexander
