There is a new series on tzadikim - we started with the Beis Yisrael of Gur. The story of the holocaust survivor from London almost knocked me off my rocker. If you liked the talk you can listen to the first two shiurim.
The shiurim should be a zechus for two people who are inspirations [among other things] in the area of getting close to tzadikim - HaRav Ariel ben Shlomit and R' Ephraim Abba ben Miriam Shoshana.
