Imitation of Christ

Fili, ego debeo esse finis tuus supremus. Ex hac intentione purificabitur affectus tuus, sæpius ad se ipsum, et ad creaturas male incurvatus. Nam si te ipsum in aliquo quæris, statim in te deficies et arescis. Omnia ergo ad me principaliter referas qui omnia sum, qui omnia dedi. Sic singula considera sicut ex summo bono manantia. Et ideo ad me tanquam ad originem suam cuncta sunt referenda.

My son, I must be your Supreme and final end, if you desires to be truly happy. Out of such purpose your affection shall be purified, which too often is sinfully bent upon itself and upon created things. For if you seek yourself in any matter, straightway you will fail within yourself and grow barren. Therefore refer everything to Me first of all, for it is I who gave you all. So look upon each blessing as flowing from the Supreme Good, and thus all things are to be attributed to Me as their source.

Imitation of Christ, III, 9:1
