As soon as Father de Bray became acquainted with her, he discovered in her one of those wonders which are wrought from time to time by grace for the confusion of the world, and set himself to second the designs of Heaven concerning this privileged soul. She too, on her side, convinced that she had at last found a guide such as she had been long seeking, bestowed on him her confidence without reserve, and continued to correspond with him as long as he lived.
In process of time, drawn more than ever by the Spirit of God, she left Château-Fort to go and seek a solitude hidden from all men; but it was almost two years before she could find what she desired. She traversed several provinces seeking for an asylum out of the reach of every human eye, until at last she arrived at the Pyrenees, where she established herself in a wild recess, which she names in her letters "the solitude of the rocks." It was a little space of a pentagonal shape, shut in by five rocks, which formed a kind of cross, and rendered the little spot of ground which they enclosed not quite inaccessible, but altogether invisible from without. From the foot of the highest of these rocks there gushed a spring of excellent water, and its summit was a kind of observatory, from whence she could espy any intruders who might venture to approach her abode. There were three grottoes at the base of the rocks, one of which was a deep and winding cavern; this she made her cell, and the two others her oratories. This solitude was at least half a league from any road, and surrounded by a thick forest, or rather by a brake, so tangled that, to get through it, the traveller must force his way among thistles and briers, by a path which seemed impracticable to any but wild beasts. Our solitary, however, met with none of these, except a bear, who was more afraid than she, and ran away. She found in her retreat shrubs which bore a fruit much like damsons; and the rocks were covered with medlar-trees, the fruit of which was excellent. The cold was not intense even in the heart of winter, while the heat of summer was tempered by the shade of the rocks, and of the woods which surrounded it. All these details are given in the letters of the solitary herself to her director, Father de Bray.
