Until her forty-fifth year her attention was given mainly to her own perfection, then she devoted herself more to others. At fifty her continual bodily afflictions became so severe that she was confined to her bed for the remainder of her life. Her spiritual guide was Luis de Ponte.
She established a branch of the Order of the Holy Saviour or Brigittines but with the rules greatly modified. By divine command, as she believed, she wrote her revelations, and when too feeble she dictated them. Luis de Ponte arranged them and left them for publication after her death. In his preface he declares his belief in their genuineness.
The writings were published in one large volume and are divided into six books containing Luis de Ponte's remarks and her own, interspersed between the visions themselves. Book I treats of the means by which God had led her; II contains revelations about the mysteries of redemption; III about God and the Blessed Trinity; IV about guardian angels and the Blessed Virgin Mary's prerogatives; V gives means to help souls in purgatory and to save souls on earth; and VI reveals her perfection as shown under terrible sufferings.
The style of the work is free and flowing and she speaks with simplicity and naïve frankness. The visions are picturesque, and pleasing or alarming according to their subject, but the descriptions are mere outlines, leaving much to the imagination, and never going into details. Their variety is greatincluding: Daily communion and Satan's objection to it; mystic espousals; how the bodies of saints can appear in visions; internal stigmata; some saints with whom modern hagiographers have dealt harshly, as St. Christopher.
Her life, so far as de Ponte had prepared it, was published at Madrid in 1664; the second part appeared there in 1673. It was translated into Latin by M. Hanel, S.J., and published again at Prague in 1672-1688, and in an enlarged edition at Naples 1690. All these editions are now very rare. A German translation in four volumes, appeared in 1861.
