His Grace shares with us some requirements for prayer in these multipart tracks. In part 3, we meditate on another requirement:

“among all other virtues undertaken by people, there is none better than [prostrations],” “it terrifies the demons.” - St. Pope Kyrillos VI

St. Isaac in homily 64 says: “More than the practice of psalmody , love prostrations during prayer"
