Yes, it's regrettably overused, and a part of all sorts of self-help (material and spiritual) phenomena, but...it's true.
You should put the first things first.
In my case, what drew me to Catholicism was not the fabulous shepherds, but Christ. Specifically, the Real Presence.
I've been re-learning that of late through this virtually-unknown treatise whose first edition dates from the second decade of the 20th Century.
It's...dense and very, very thorough. Too many of the footnotes are in Latin. But it is a real masterpiece, repaying re-reads of each page. I'm only 50 pages in, but I am truly inspired by it. The book starts with a discussion of what constitutes a "sacrifice," examines Christ's on Golgotha and works its way from there. Brilliant, and back in print (not sure which edition) from a reprint house, it is a meditation on the Cross and the Mass. One that deserves to be better known. Tolle, lege.
