St. Teresa made prayer the foundation of the life of her daughters and their primary activity.  For this reason, the Church asks all Teresian monasteries to enter into the mystery of  contemplative prayer and to offer an exemplary witness to it among God's People.  The Carmelite Nun imitates the life of Christ contemplating on the mountain.  She thereby gives witness in the Church to a life of unceasing prayer.

The day is made up of personal and liturgical prayer.  St. Teresa longed to contribute to the building up of the Body of Christ.   She felt that the best way to do this was by prayer and living according to the Gospel. Prayer and immolation would be the Nun's service to the Church.  United with Christ, the Nuns offer themselves and their prayers for the People of God.
