Everything a monk does is meant to be a prayer, a communion with God. Formal prayer, however, is a primary means of achieving this union. His day is centered around three vital elements: the Conventual Mass, a communal celebration of the Eucharist; the Liturgy of the Hours, the Church's singing of psalms to consecrate the morning, mid-day and evening; and lectio divina, the ancient monastic practice of meditative reading of Sacred Scripture and other writings from a rich spiritual tradition. Lectio, which derives from one of the earliest forms of Christian prayer, is a spring refreshing the monk in his daily quest for God and reinvigorating the zeal with which he approaches his work.
