“Fasting is a beautiful and great act for the soul, but also for one’s health too. Let us recall how the lives of our beloved saints sound: ‘This ascetic in a waterless desert, where there was no one, neither ate nor drank, he ate food only every three days, was weary from the cold and frost, and at the age of 107 peacefully departed to the Lord.’ This is the refrain of their lives.”
(Metropolitan Tikhon Shevkunov in “The Life of a Christian”)
