Catalina Rivas has some wonderful writings on such topics as the Holy Sacrifice of the Mass, on Adoration of the Blessed Sacrament, the Sacrament of Confession, Sacrament of the Anointing of the Sick and more. I am reading her meditations on the Mass and Adoration presently. I would recommend them. Most of her works can be downloaded for free or even printed up at home or purchased for a nominal fee. I could never think of such lovely thoughts myself and they are an aid to me in praise of God. Take a look: http://www.loveandmercy.org/
