Great point. I have forgotten about this. There were at least 2, one heavy, one less so, periods early on of pretty profound depression. The first lasted maybe 2 or 3 days. It was a dark hole of just a profound sense of loss. I was taken back at first and questioned what I was getting into and stopped meditating for a few days but I got through it. I wish I could edit my comment to add this warning. Thank you for bringing this up.
