In the same way our soul, if it is not weighed down with faults that touch it, and the cares of this world, or damaged by the moisture of injurious lusts, will be raised (so to speak) by the natural blessing of its own purity, and carried aloft to the heights by the light breath of spiritual meditation. Leaving things low and earthly, it will be transported to those that are heavenly and invisible.
St. John Cassian
