Once you enter a weakened state in the dryfast your power increases exponentially and only increase the longer you dryfast. As long as you aren’t in a detox crisis. Day 3 and later the power intensifies rapidly. It’s easier to let go, well actually it becomes more automatic you don’t have to try because in the dryfast your energy is releasing from you and naturally moving outward. And it’s easier to feel the smallest bit of emotions magnified within you. Your vibration changes easier with little resistance and time and space is shortened as things manifest in the shortest amount of time.
I think it is the combination of an increase in free time (no food related activity) and the fact you are making your body hypersensitive to pleasure (specifically dopamine & endorphins). I imagine too that the focus you get from ketosis is an evolutionary trait that developed to help you find food easier too. It truly is a superpower!
