Oh, how happy a chance is this for the soul which can free itself from the house of its sensuality! None can understand it, unless, as it seems to me, it be the soul that has experienced it. For such a soul will see clearly how wretched was the servitude in which it lay and to how many miseries it was subject when it was at the mercy of its faculties and desires, and will know how the life of the spirit is true liberty and wealth, bringing with it inestimable blessings.
