We are told to pray unceasingly, and so even during the night, our waking moments can be spent wisely by praying.
It is so easy for our minds to become cluttered with the debris of daily life. Prayer is my choice of clearing away all the trash that inundates us, and at the advice of my Confessor, I am currently reading Introduction to the devout Life by St. Francis De Sales. My goal is to become proficient at mental prayer, as was my patron Saint, Teresa of Avila. St. Alphonsus Ligouri writes, "It also helps us very much to obtain divine grace if we have recourse to the intersession of the saints, for they have great power with God, especially for the benefit of those who are their special clients."
And so I have confidence that St Teresa will aid me in my goals, and help me in my journey of attaining salvation.
