Eucharistic Devotion
Around the Real Presence — the prayers before and after Communion, the hymns of adoration, the Holy Hour, and the great spiritual treasure of the visit to the Blessed Sacrament.
Adoro te devote, latens Deitas — "I adore Thee devoutly, hidden God." The Eucharist is the Catholic life in concentrated form, and the prayers gathered here are how the saints have learned to stay near it. Anchor practices: a moment of preparation before Mass, a thanksgiving after, a daily visit to the tabernacle, and an hour of adoration each week.
Before & After Communion
What to pray when you come to the Lord, and what to pray when He has come to you.
Spiritual Communion
When sacramental Communion is not possible, the soul still goes to Him.
Adoration & the Holy Hour
The simple visit to the tabernacle and the formal Hour of reparation — both of them, simply, time spent with Him.
Eucharistic Hymns
The Aquinas hymns of Corpus Christi — the foundation of every Benediction and Holy Hour. Pange Lingua (with its excerpt Tantum Ergo), Sacris Solemniis (with Panis Angelicus), Verbum Supernum (with O Salutaris Hostia), Adoro Te Devote, and the sequence Lauda Sion Salvatorem. The full Office (with the Mass Cibavit) is in the linked book.
