A couple of weeks ago, a yoga friend's mother passed away. She was 101 and my friend was her caregiver for something like 15 years. My friend said she'd gone on a "great svasana."
Then this past Tuesday my Mother-in-Law passed. She was found around 9 or 9:30 p.m, so she must have stopped breathing pretty quickly after falling asleep.
My Mother-in-Law never liked being old. She started saying 25 years ago that she was ready to die. She didn't like being tired. Being achy, having all the gastro-intestinal issues that she did. She was tired of people, food, and going places. She used to say regularly that she just wanted to die. Not in a whiny sort of way. Just that it was time to check out. We actually had to ask her to stop saying it in front of the children. When they were little they would hear her say it and wonder about it. No little kid wants to hear their beloved grandparent say she doesn't want to live anymore.
So I think passing away was truly a great svasana for her. She is finally at complete rest.
