The Forward has a beautiful article on Rav Kaduri, ztz"l. It closes this way:
Just as I was about to leave, an elderly Kabbalist was brought near to the grave to pay his respects to his colleague. Women asked for his blessing on behalf of sick or barren relatives, and he obliged — even, once, over a cell phone. Then he told us that we should begin the Sabbath an hour early this week and that by Kadouri's merit, we would enjoy peace and long life. I'm thinking about doing it — after all, you never know.
