Obsecro te, angelice spiritus, cui ego ad providendum commissus sum: ut custodias me indesinenter, protegas, visites, et defendas ab omni incursu diaboli. Vigilantem atque dormientem, nocte ac die, horis continuis atque momentis confove me. Ubicumque iero, comitare mecum. Repelle a me per virtutem Dei omnem tentationem satanae: et quod mea non exigunt merita tuis precibus obtine apud misericordissimum iudicem, ut nihil in me habeat locum contrariae virtutis admixtio. Cumque me per abrupta vitiorum de via esse videris, per semitas iustitiae incedendo ad redemptorem meum reducere satagas et, in quacumque necessitate vel in quacumque angustia me esse perspexeris, auxilium Dei omnipotentis tuo obtentu super me adesse sentiam.

Precor te custos meus ut si fieri possit notum mihi facias finem meum. Et, cum de hoc corpore ductus fuero, non dimittas malignos spiritus terrere me aut illudere, neque in foveam desperationis inducere. Et non derelinquas me, iubente Deo, donec ad visionem conditoris mei perducas, in qua simul et ego pro opere et tu pro custodia mea una cum beatissima Dei genetrice sanctisque angelis et omnibus sanctis perenniter laetemur. Amen.

I beseech thee, angelic spirit, to whose care I have been committed: guard me without ceasing, protect me, visit me, and defend me from every assault of the devil. Waking and sleeping, by night and by day, every hour and every moment, cherish me. Wherever I go, go with me. By the power of God drive from me every temptation of Satan; and what my merits cannot claim, obtain by thy prayers from the most merciful Judge, that no admixture of the contrary power may find any place in me. And when thou seest me gone from the way over the precipices of vice, labour to bring me back to my Redeemer along the paths of justice; and in whatever need, in whatever strait thou seest me, let me feel the help of almighty God present over me through thy protection.

I pray thee, my guardian, if it may be done, to make my end known to me. And when I am led out of this body, do not let the evil spirits terrify me or mock me, nor lead me into the pit of despair. And do not forsake me, at God's command, until thou hast brought me to the vision of my Creator, in which I for my work and thou for thy guardianship, together with the most blessed Mother of God, the holy angels and all the saints, may rejoice for ever. Amen.
