I have sought earnestly and with great diligence that good and high virtue by which man may draw closest to God... and as far as my intelligence would permit, I find that high virtue to be pure disinterest, that is, detachment from creatures. Our Lord said to Martha 'Unum est necessarium', which is to say; to be untroubled and pure, one thing is necessary and that is disinterest.
