Eucharistic Adoration is not subject to a particular formula. There are many things a person can do. For example:
–enjoy the great privelege of gazing upon the Lord in the Eucharist.
–say prayers of thanksgiving
–ask God for forgiveness and the grace to remove your imperfections.
–pray for peace.
–pray for the end of abortion.
–pray that your relationship with the Lord will grow.
–pray for the grace to open every door and window to your heart, mind, and soul.
–pray for the grace to detach yourself from the things of this world.
–pray for the grace to put Jesus first and foremost in your life.
This list could be extended to include an incredible number of different things. I also like to read and meditate on scripture and to read and to sing, non-audibly of course, hymns of worship and praise.
Just go for it and let the Lord have his way with your spiritual life.
