True fasting…

The essence and power of abstinence is not in refraining from food, but in expelling from the heart every remembrance of evil and other such things. That is true fasting, and what – above all else – the Lord demands.
–Saint Leo of Optina (1768-1822)

The nature of love…

This is the nature of love: to the extent that we distance ourselves from the center of the circle and do not love God, we distance ourselves from our neighbor; but if we love God, then the nearer we draw to him in love, the more we are united with our neighbor in love.
–Saint Dorotheus of Gaza (Sixth Century)
