The Tradition of the Church proposes to the faithful certain rhythms of praying intended to nourish continual prayer. Some are daily, such as morning and evening prayer, grace before and after meals, the Liturgy of the Hours. Sundays, centered on the Eucharist, are kept holy primarily by prayer. The cycle of the liturgical year and its great feasts are also basic rhythms of the Christian's life of prayer.
