Ah, this is a wonderful idea.
I started to read and contemplate about "The Middle Way of Nagarjuna" (Madhiamika-śastra - translated from Chinese to German). This is a big project for me, because I read very slowly. I was looking for someone to join me, but there are not many who are able to understand it or who are interested at all.
So now I can not join your group about the "Jewel Ornament", because I don't want to lose my train on thought with Nagarjuna.
But I'm so slow - maybe you can join me, when you have finished the studies on your book.
