Of all the virtues, and if virtue constitutes virtue, purity is perhaps the most difficult to grasp.
It is an obvious and a mystery because only nothing is pure, but nothing is nothing.
Purity does not reside in ignorance or in the absence of desire, but in desire without fault and without violence, in desire that is accepted, shared, elevates and celebrates.
It is the sweetness, the peace and the innocence of desire that allow us to approach sacred things without tarnishing them and without losing ourselves in them.
Everything that we do unwillingly or with an evil will is impure.
Purity is not a thing, nor even a property of reality, but a certain way of loving.
