And without this purgation it will be wholly unable to feel or experience the satisfaction of all this abundance of spiritual sweetness. For one single affection remaining in the spirit, or one particular thing to which, actually or habitually, it clings, suffices to hinder it from feeling or experiencing or communicating the delicacy and intimate sweetness of the spirit of love, which contains within itself all sweetness to a most eminent degree.
