"But I do not grant the consolation of My visitations in one way alone, which would appear as if I had but one way in which to do so, but I grant it in diverse ways, according as pleases My goodness, and according to the need and the necessity of the soul. But the soul, in her ignorance, will, nevertheless, seek My consolations in that way alone which she has experienced, thereby, as it were, imposing laws on the Holy Spirit.
She should not do so, but should pass on courageously by the doctrine of Christ crucified, receiving what it pleases My Goodness to give her, and in the manner, time and place that I choose. And if, nevertheless, I give not, it is through love and not through hatred, and that she may seek and love Me in truth, and not for her own delight, receiving My charity with humility [...]
Such as these, of whom I have spoken, desire to choose their own consolations in their own way, and so to go through life, and their ignorance is at times so great that, having imagined a particular consolation, and I, visiting them in any way except that of their imagination, they will resist Me and will not receive Me. A soul who would act thus is deceived by her own pleasure and spiritual delight, for it would be impossible to remain always in one state. She must either go forward to the virtues or turn right backwards. And neither could the mind remain stationary in the enjoyment of one delight alone without My Goodness increasing that delight. Many are the kinds of delights that I give to the soul [...]
These various methods I use through love to preserve her and to increase, in her, humility and perseverance, and to show her that she need place no rules for me, nor seek her end in consolation, but only in virtue founded in Me, and to teach her with humility to receive what I choose to give her in My own time and manner, and to believe, with lively faith, that I give as her welfare demands or as is needed to bring her to great perfection."
