Hello Gallen
You've touched on a point that I'm fairly keen to pursue. That is the denseness of the pelvic and tailbone region which I have to admit I'm working hard to open because I do find myself very tight and extremely sore and painful in both regions but especially the tailbone when sitting in a meditative pose for any longer than forty minutes (only very gradually getting better by the day).

My aim is to achieve full lotus sitting as well and I wondered how long you practice in the sitting position at any one time and over how many months.

As I said before, the longest I've been able to achieve without too much pain is forty minutes. Should I also try using Master Lin's exercises for this more regularly?

As usual, your wisdom and insight is invaluable!
Much warmth
Jetay
