The wondrous shock of feeling had come like the earthquake which shook the foundations of paul and silas s prison ; it had opened the doors of the soul s cell and loosed its bands - it had wakened it out of its sleep, whence it sprang trembling, listening, aghast ; then vibrated thrice a cry on my startled ear, and in my quaking heart and through my spirit, which neither feared nor shook but exulted as if in joy over the success of one effort it had been privileged to make, independent of the cumbrous body

To pass its threshold was to return to stagnation ; to cross the silent hall, to ascend the darksome staircase, to seek my own lonely little room, and then to meet tranquil mrs. fairfax, and spend the long winter evening with her, and her only, was to quell wholly the faint excitement wakened by my walk, - to slip again over my faculties the viewless fetters of an uniform and too still existence ; of an existence whose very privileges of security and ease i was becoming incapable of appreciating
