Yes. For the four tris I've done, I have felt that way. It has something to do with being able to turn inwards and focus, without distractions. Happy to see folks after, but not before and I don't even care about during.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
