The only time I felt something more powerfully relaxing was after floating in a sensory deprivation tank or "float tanks." I recommend this healing modality to anyone and everyone. It is so relaxing and easy. I know the name "sensory deprivation" and "isolation tank" sounds somewhat intimidating, but I promise you it is so cool and not scary at all. I remember the first time I floated was in the middle of doing my first juice cleanse and my body released so much stress and tension in that water that I felt like I inhabited a whole new body when I stepped out.
I really like the way Joe Rogan describes his experiences with the float tanks in this video. There is some foul language (be warned) and he gets pretty deep ( I love it haha).
Lie he said, you have to get in the tank a few times before you really start to drop the mind. My first experiences really relaxed my body and released tension more than anything else. My being felt very calm afterwards as well.
