Adoration is an ancient tradition of the Church. As Catholics we believe that at the consecration during the Mass, the bread and wine cease to exist and in their place are the body and blood, soul and divinity of Jesus. This is the Eucharist.
When we pray to Jesus who is before us as the Eucharist, we adore him. This is what adoration is.
