The lax discipline and somewhat worldly tone of the place proved a great surprise to her, as she had imagined that the odor of sanctity must be all-pervasive in a religious house; but she evidently accommodated herself to the conditions as she found them, for she made no decided protest and gave evidence of no special piety until twenty years after she had formally given up the world. Then, saddened and sobered by her father's death, Teresa began to have wonderful trances, accompanied by visions wherein Christ, crucified, appeared to her time and time again. Although in later times these unusual experiences have been adduced to prove her saintship, at the time of their occurrence they were not looked upon in the same light, and there were many who said that Teresa was possessed of devils. She was more than half inclined to this view of the case herself, and the eminent religious authorities who were consulted in the matter advised her to scourge herself without mercy, and to exorcise the figures, both celestial and infernal, which continued to appear before her. The strange experiences continued to trouble her, however, in spite of all that she could do, and to the end of her days she was subject to them. Constantly occupied with illusions and hallucinations, she soon became a religious mystic, living apart from the world and yet deeply interested in its spiritual welfare. One of her visions in particular shows into what a state of religious exaltation she could be thrown. She imagined herself a frameless mirror of infinite size, with Christ shining in the middle of it, and the mirror itself, she knew not how, was in Christ!
