I did a 3-day mental cleanse in Shanghai back in March, 2017. It was the first time that I ran this event. Sitting down on the chair starting at 8:30 in the morning, lunch in between and last sitting that usually ended around 6:30p.m. It was held at a very nice Buddhist studio that was recommended by a dear friend.
It was a really dear experience to sit and explore possibilities with everyone that sat with me, both on the hot seat and the hard small chairs. We all went through the transformation together. I heard laughter, tears, faces of contemplation, men and women with faces of young children that started to change and grew up.
