But David explained to her that her notions on this subject were quite erroneous, and proved from many Bible texts, and from his own example, that dancing was most assuredly a sanctified occupation for the blessed. But what was wanted just now was an immediate decision, Yes or No, whether she wished to enter into eternal joy by way of temporal self-denial or not. If she did not, then he would go farther on; for they wanted some dancers in Heaven. Musa stood, still doubtful and undecided, and fumbled anxiously with her finger-tips in her mouth. It seemed too hard never to dance again from that moment, all for the sake of an unknown reward. At that David gave a signal, and suddenly the musicians struck up some bars of a dance of such unheard-of bliss and unearthliness that the girl's soul leapt in her body, and all her limbs twitched; but she could not get one of them to dance, and she noted that her body was far too heavy and stiff for that tune. Full of longing she struck her hand into the king's, and made the promise which he demanded. Forthwith he was no more to be seen, and the angel-musicians whirred and fluttered, and crowded out and away through an open window; but, in mischievous, childish fashion, before going, they dealt the patient stone angels a sounding slap on the cheeks with their rolled-up music. Musa went home with devout step, carrying that celestial melody in her ears; and, having laid all her dainty raiment aside, she got a coarse gown made and put it on. At the same time, she built herself a cell at the bottom of her parents' garden, where the deep shade of the trees lingered, made a scant bed of moss, and from that day onwards separated herself from all her kindred, and took up her abode there as a penitent and saint. She spent all her time in prayer, and often disciplined herself with a scourge. But her severest penance consisted in holding her limbs stiff and immovable; for whenever she heard a sound, the twitter of a bird, or the rustling of the leaves in the wind, her feet twitched, as much as to tell her they must dance. As this involuntary twitching would not forsake her, and often seduced her to a little skip before she was aware, she caused her tender little feet to be fastened together by a light chain. Her relatives and friends marvelled day and night at the transformation, rejoiced to possess such a saint, and guarded the hermitage under the trees as the apple of their eye. Many came for her counsel and intercession. In particular, they used to bring young girls to her who were rather clumsy on their feet; for it was observed that every one whom she touched at once became light and graceful in gait.
