I don't know what category this fits into,so I'll just put it here.
In January my mother passed on.
As my extended family and I were praying over her body right after she passed,I happened to glance around the room and saw our prayers as a thin smoke rising to Heaven.
The room was filled with this thin blue/gray smoke slowly going up and out through the ceiling. I knew the smoke was our prayers and I watched with the most peaceful heart! Visible prayers, I am so comforted by the memory of them.
