God alone knows how to exercise the soul in virtue, and the Holy Spirit is its only true master in the spiritual life.

Not only did the spirit of God excite and elicit in me voluntary acts of self-abandonment, but often my soul was as if stripped of all support, and placed, as it were, over a dark and unfathomable abyss, and thus I was made to see that my only hope was to give myself up wholly to Him.

The words of Job well express this purgation of the soul when he says: 'The arrows of the Lord are in me, the rage whereof drinketh up my spirit, and the terrors of the Lord war against me.' (Here follow other quotations from the book of Job.) Sometimes these pains penetrate into the remotest and most secret chambers of the soul.

The faculties are in such an intensive purgation that from the excessive pain which this subtile and purifying fire causes they are suspended from their ordinary activity, and the soul, incapable of receiving any relief or escaping from its suffering, has nothing left but to resign itself to the will and good pleasure of God.

Though enveloped with an unseen but no less real fire, suffering in every part, limb, and fibre from indescribable pains, fixed like one who should be forced to look the sun constantly in the face at midday, she is nevertheless content, for she has a secret consciousness that God is the cause of all her sufferings, and not only content--she would suffer still more for His love."
