Question: What are we supposed to do during the adoration of the Blessed Sacrament?
Answer: Ideally prayer is a direct dialogue between God and man, but not everyone is blessed with this ability, and not at all times or in all places. One of the reasons for exposition of the Blessed Sacrament is to aid the powers of our mind to focus on the intangible God with something perceptible to the senses.
Still, many of us find that our prayer is limited to meditation on the truths of the Faith or on the events in the lives of our Lord and Lady. Properly said, the Rosary is an example of the latter, and is often prayed before the Blessed Sacrament. Sometimes we must rely on prayers and other holy inspirations that have been prepared by others - either from memory or out of a book. There is nothing wrong with reading the Gospels or a Life of Christ, praying the Office or other devotion, or reading some other spiritual material, but do try to remember that the Jesus about whom you are reading is the same Jesus who is on the altar or in the tabernacle!
