I might say to you, my dear Sister, what our Lord said to Martha! Why so much solicitude and trouble? How can you still confound, as you do, the care that God commands you to take about your salvation, with the uneasiness that He reproves? As you try to abandon your temporal affairs to divine Providence while taking care at the same time not to tempt God; do the same for your spiritual progress, and, without neglecting the care of it, leave the success to God, hoping for nothing except from Him. But do not ever dwell on such diabolical thoughts as: I am always the same, always as little recollected, as dissipated, as impatient, as imperfect. All this afflicts the soul, overwhelms the heart and casts you into sadness, distrust and discouragement. This is what the devil desires; by this pretended humility and regret for your faults he is delighted to deprive you of the strength of which you have need for the purpose of avoiding them in future, and of repairing the harm they have done you. Bitterness spoils everything and on the contrary gentleness and sweetness can cure everything. Bear with yourself therefore patiently, return quietly to God, repent tranquilly, without either exterior or interior impetuosity but with great peace. If you act thus you will gradually become calm, and this practice will cause you to make more progress in the ways of God than all your agitations could possibly effect. When one feels a little peace and sweetness interiorly it is a pleasure to enter into oneself and one does so willingly, constantly, without any trouble, almost without reflexion.
Believe me, my dear Sister, and place your whole confidence in God through Jesus Christ; abandon yourself more and more entirely to Him, in all, and for all, and you will find by your own experience that He will always come to your assistance when you require His help. He will become your Master, your Guide, your Support, your Protector, your invincible Upholder. Then nothing will be wanting to you because, possessing God you possess all, and to possess Him you have but to apply to Him with the greatest confidence, to have recourse to Him for everything great and small without any reserve, and to speak to Him with the greatest simplicity in this way: "Lord, what shall I do on such an occasion? What shall I say? Speak, Lord, I am listening; I abandon myself entirely to You; enlighten me, lead me, uphold me, take possession of me."
I am sorry for the difficulties and worries of which you tell me, but recollect that patience and submission to God in the midst of annoyances that are permitted by His providence will enable you to make more progress than the quietest and most recollected life. The latter always tends to flatter self-love; the former, on the contrary, afflicts and crucifies it, and thus makes us attain true peace of mind by union with God. When you find yourself in such utter dejection that you cannot make a single act of any virtue whatever, beware of tormenting yourself by violent efforts but keep simply in the presence of God in a great silence of utter misery, but with respect, humility and submission like a criminal before his judge who sentences him to a chastisement he has well merited: and understand that the interior silence of respect, humility and submission are worth more and purify better than all the acts that you, uselessly, force yourself to make, and which only serve to increase the trouble of the soul. The character of the person to whom you allude is very good, I own; but while praising God for all the good gifts He has bestowed upon her you ought not to despise the share He has given to you. On the contrary, by your submission to, and respect for the designs of God you must wish to be such as He wishes you to be, without, however, neglecting to correct yourself. The greatest improvement I desire to see in you is, that your mind may never get embittered for any reason whatever, and that you always treat yourself gently. Is it not true that you behave thus towards your neighbours? You are not always reproaching them bitterly and continually about their characters, but you try gently to induce them to reform. Do the same to yourself, and if gradually this spirit of gentleness should take root in your heart you would soon make progress in the spiritual life and without so much trouble. But if the heart is continually filled with feelings of harshness and bitterness, nothing much can be achieved and everything costs great effort. I insist greatly in this matter because it is an essential one for you, and in your place I should apply myself seriously to acquire a great interior and exterior gentleness in all things just as if there were no other virtue to practise; for this will, in your case, bring all the others in its train. I appeal to your own experience about it. After having worked at it for some time very quietly, without the interruption of those impetuosities and hurries which drive away all sweetness and prevent you gaining the victory, you should be able to recognise the fact, that in this way much more is gained without half the fatigue.
