In several books I found different methods to approach God and various practices of the spiritual life that I feared would burden my mind rather than facilitate what I wanted and what I sought, namely, a means of being completely disposed to God.
This led me to resolve to give all for all. Thus, after offering myself entirely to God in atonement for my sins, I renounced for the sake of his love everything other than God, and I began to live as if only he and I existed in the world.
Sometimes I considered myself before him as a miserable criminal at his judge’s feet, and at other times I regarded him in my heart as my Father, as my God. I adored him there as often as I could, keeping my mind in his holy presence and recalling him as many times as I was distracted.
I had some trouble doing this exercise, but continued in spite of all the difficulties I encountered, without getting disturbed or anxious when I was involuntarily distracted.
I was as faithful to this practice during my activities as I was during my periods of mental prayer, for at every moment, all the time, in the most intense periods of my work I banished and rid from my mind everything that was capable of taking the thought of God away from me.
