Tefillah beHispa’alus: Building the Temple Within – part 1
This was a webinar given for The Mussar Institute on 3-Mar-2014. Class 1 of 2. (Part 2 is here.)
The format is more introducing and practicing tools for kavanah than a class in the meaning of the words of the siddur.
Audio only version is available here.
(Admittedly this is a good deal of the blind leading the blind.)
