'Do not neglect to make due preparation for the Holy Sacrifice; always make your thanksgiving; watch day and night over the interior tabernacle, that is, the heart of the worthy priest. He who acts thus will not fail to enkindle within himself the fire of divine love. Guard cautiously this living tabernacle, and keep always burning there the lamps of faith and charity. May it be ever adorned with virtues! Imitate the perfect dispositions of your Saviour. Since the Mass is the renewal of the Sacrifice of the Cross, enter into the sentiments of compunction and of love which animated the Blessed Virgin, St. John, Joseph of Arimathea, and Nicodemus. The heart of the priest ought to be the sepulchre of Christ. As the tomb in which He was laid after death was new, so ought your heart be pure, animated with a lively faith, a firm confidence, an ardent charity, a fervent desire for the glory of God and the salvation of souls. The Mass is the most favorable occasion to treat with the eternal Father, because then we offer Him His only Son as a victim for our salvation. Before celebrating, reflect on the sufferings of your Redeemer, commune peaceably with Him, even in the midst of dryness; carry to the altar the needs of the entire world.'
