Baring-Gould’s sources: Authorities:—The lives of S. Bridget.
Amongst the nuns of S. Bridget's monastery of Kildare, there was one named Darlugdach. When young, she followed S. Bridget, and being very dear to her, slept with the abbess.
Darlugdach, not guarding her eyes with sufficient strictness, saw, and fell in love with a man, who also became enamoured of her, and their ardent glances revealed their mutual passion. A plan was formed that she should elope with him, on a certain night; and she laid herself in the bosom of the sleeping abbess with beating heart, troubled by a conflict between duty and passion. At last she rose, and in an agony of uncertainty, cast herself on her knees, and besought God to give her strength to master her love, and then, in the vehemence of her resolve, she thrust her naked feet into the red coals that glowed on the hearth, and held them there till the pain had conquered the passion. After that, she softly stole into bed again, and crept into the bosom of her holy mother. When morning broke, Bridget rose, and looked at the blistered and scorched soles, and touching them, said gently, "I slept not, dear child, but was awake, and saw thy struggle, and now, because thou hast fought valiantly, and hast conquered, the flame of lust shall no more hurt thee." And she healed her feet.
Darlugdach, as has been related in the life of S. Bridget, besought her spiritual mother to let her die with her, but S. Bridget promised that she should follow on the anniversary of her departure, after the expiration of a year. And so it was.
