I neglected to write about those infused commentaries that acquired on your knees.
The best commentary free of charge is in Adoration of the Most Blessed Sacrament and also just plain old visiting the Prisoner of the Tabernacle and saying hello to the Little Flower, who desired her whole life to be in their with Him.
The second best commentary available is the Little Office of the Blessed Virgin Mary.
The best Gospel commentary I have come across is the Rosary.
