Let us make friends with our Holy Guardian Angels, and follow in the example of the Patron of Youth, Saint Aloysius Gonzaga!  Lets get into the good habit of commending one-self under the protection of the holy Guardian Angel not once but three times a day.  Also when you read  and pray say, 'I read with my holy Guardian Angel.'  "I pray with my holy Guardian Angel.'  Your reading and prayers will be moments of great joy and your holy Guardian Angel will impart heavenly wisdom.
