When the power of the Holy Spirit dominates the soul and guides it, then, instead of the written commandments and laws of the Holy Scriptures, the Holy Spirit’s commandments take root and sprout in the heart.
It is then that man is taught the secrets of the Holy Spirit, and no longer needs the help of the written words of the Holy Scriptures, so that the memory of the words of God remains harmless, far from the danger of error and oblivion.
