Part III-3. Eucharistic Devotions
58. Devotion, both private and public, toward the sacrament of the altar even outside Mass that conforms to the norms laid down by lawful authority and in the present Instruction is strongly advocated by the Church, since the eucharistic sacrifice is the source and summit of the whole Christian life. 
In structuring these devotional exercises, account should be taken of the norms determined by the Vatican Council II concerning the relationship to be observed between the liturgy and other, nonliturgical sacred services. Particular attention should be paid to this one: "These devotions should be so fashioned that they harmonize with the liturgical seasons, accord with the liturgy, are in some way derived from it, and lead the people to it, since, in fact, by its very nature far surpasses any of them."
