Elder Cleopa (Ilie) of Sihastria: Begin with the sign of the Cross

Do not begin anything without first signing yourselves with the holy cross! When you leave on a journey, when you begin school, when you are along and when you are with other people, seal yourselves with the holy cross on your forehead, your body, your heart, your lips your ears, etc. Let your entire being be sealed with the sign of the victory of Christ, over hell.
Elder Cleopa (Ilie) of Sihastria, from Elder Cleopa of Sihastria: In the Tradition of St. Paisius Velichovsky, by Archimandrite Ioanichie Balan, chapter 5, Counsels to Laity.
