There is a certain method of prayer which is both very easy and very useful. It consists in accustoming our soul to the presence of God, in such a way as to produce in us a union with Him which is intimate, simple, and perfect. Oh what a precious kind of prayer is this! -St. Francis de Sales
St. Aloysius Gonzaga found nothing easier than to keep his mind constantly united to God, so that he had as much difficulty in turning his thoughts from Him, as others have in keeping them fixed in that direction.
It is narrated in the Lives of the Fathers, that a holy Abbot instructed one of his novices that he should take care never to lose sight of God, and think of Him as always present. “For,” said he, “this is the rule of rules, and the one which the Lord taught to Abraham, when He said, “Ambula coram Me, et esto perfectus” — Walk before Me, and be perfect. This was so impressed on the mind of the young man, that he practised it wonderfully well; and from the reckless youth that he was, he became a monk so perfect, that when he died, a few years after, he was seen to fly directly, and with great glory, into heaven.
