I took for my advocate and lord the glorious Saint Joseph and commended myself earnestly to him; ...This has also been the experience of other persons whom I have advised to commend themselves to him; and even to-day there are many who have great devotion to him through having newly experienced this truth.
I have never known anyone to be truly devoted to him and render him particular services who did not notably advance in virtue, for he gives very real help to souls who commend themselves to him. For some years now, I think, I have made some request of him every year on his festival and I have always had it granted. If my petition is in any way ill directed, he directs it aright for my greater good.
