"Perpetual Eucharistic Adoration is the adoration of Jesus Christ present in the Holy Eucharist. In the many Churches that have this adoration, the Eucharist is displayed in a special holder called a monstrance, and people come to pray and worship Jesus continually throughout the day and often the night. Christ's great love for us was shown when he was crucified on the cross to pay the penalty for our sins and give us eternal life. He loves us without limit, and offers Himself to us in the Holy sacrament of the Eucharist. Can we not give Jesus a few minutes of love and adoration in return?" (From The Real Presence Eucharistic Education and Adoration Association.)
During adoration of the Blessed Sacrament you can pray the rosary, read the Bible or say your own prayers. This is a quiet time with the Lord. This is a very peaceful and healing time. There will also be time for singing, a quiet time and Benediction.
