“Let each one deny himself some food, drink, sleep, needless talking and idle jesting, and look forward to holy Easter with joy and spiritual longing.”

- Rule of St. Benedict, on the observance of Lent

“Do not love the world or the things in the world. If any one loves the world, love for the Father is not in him.For all that is in the world, the lust of the flesh and the lust of the eyes and the pride of life, is not of the Father but is of the world.And the world passes away, and the lust of it; but he who does the will of God abides for ever.”

1 John 2:15-17
