Yeah, I did lots of 10 day retreats at Goenka's centers for many years. I was able to work with him several times and his advice was so helpful. We meditated from 4am to 9pm for an hour to 3 hours at a time with breakfast and lunch breaks.
I miss retreat work, I haven't been to a retreat for about 5 years, I am looking forward to checking out Bhante G's center.
