There are several ways to detoxify the physical body, and perhaps they serve either as a metaphor or even quite literally also for other ways of looking at the body, such as the spiritual, emotional or psychological body.
In the void experience, everything’s adrift. Laws such as gravity don’t even seem to work. I’m talking about those times in life when we feel like we’re in a spiritual vacuum.
The physical body gets rid of toxins via fasting and by sweat. Either way, for the body to reset it needs to stop ingesting so that it can focus on evacuation for a time. When fire and rain fuse, you get steam. Steaming out the toxins in a sweat lodge is a great way to experience fusion in the void. Spiritually, what do fire and rain mean as a metaphor? If you’re in a void, what do you bring together to create spiritual steam, to heat it up and eliminate toxins? Exercise, fasting, all these things are known to assist not only the physical body but also nourish the spiritual body as well.
Steam. In the water, toxins are trapped and evaporate through the skin. In the void God does provide fusion. It’s not a fusion to move forward, yet. It’s a fusion designed for a purification process. You can take a proactive engagement with this particular fusion. It requires little effort. In fact, in some ways it takes more effort to eat than to fast. (Cook, sit down for a meal, wash your dishes.) In some ways it takes more energy to be unfit, to not sweat, than it does to get out and walk for an hour, or to go to a sauna. (Certainly not at first).
I am not advocating a lifestyle where you never eat and also run ten miles a day. All things in balance. Fire and rain fuses in the void for purity.
