The thing with the jacuzzi is that when in it, I'm able to let go of thoughts and feelings, especially when I turn the bubbles on. The feeling of comfort is not so much arrived at because of the sensation of bubbling water against your body, but of you yourself 'becoming part of the water', so to speak, there no longer seems to be much of a 'self'. I guess it works like a sort of regression to the womb. It is different from, e.g. being massaged: when you receive a massage, it feels good too, but you do not become one with the massage therapist. At least I don't ;-)
