SAINT THOMAS was a "remarkably contemplative man." What does that mean
That means that he lived in God, and God in him, a life of tender affection.
His soul, his intelligence, his heart, his will, were opened wide towards heaven, and he received light like the sun, grace like dew, and all his life was like a garden full of many different flowers and fruits.
He prayed without ceasing. Even at night he hardly stopped praying.
He said holy Mass with such love for Jesus, that in remembering His painful Passion, very often he broke into tears and wept so long that his brothers had to approach him and touch him, so that he would come back to himself and would go on with the Mass.

You already know how deep was his devotion to the Blessed Sacrament. It was this great love of the Eucharist and the exceptional knowledge that God gave him of this Mystery of Faith that permitted him to write the Office of the Blessed Sacrament.
It was to the altar that he went to seek light. With his head against the tabernacle "he would stand there with many tears and shaking with sobs, then he would come back to his cell and continue his writing."
