I've explained fasting on here a few times over the years.
I don't do it for "spiritual" reasons
but some surfing mates got me onto Ehret when I was 18.
I read up and started to experiment.
Was very impressed when I fell a storey onto rusty nails puncturing my thigh deeply
which became badly infected & swollen.
Rather than go to a doctor, young & stupid, I went onto a water fast.
After a week I squeezed the leg & a huge amount of pus ran out
(I mean a river that covered my hands)
and it subsequently healed with a moderate scar.
So I was convinced of the healing benefits.
and shown that fasting has a psychological component;
I now KNOW that I can survive, without eating, for a week minimum
which is a good thing to know in an emergency.
I now KNOW that daily hunger is largely a habit.
that TRUE hunger doesn't arise for at least a week in mild weather with mild exertion
(I've surfed big Sunset Beach 4 days into a water fast)
despite craving, salivation at the aroma of food & FEAR OF MISSING OUT.
Yearly fasting MAKES me make time for myself, my body, my health.
At one stage, when I was a teacher,
I lived in a tent for a week next to a beach in the middle of summer,
doing nothing but sleep, swim in the ocean & read
but I've also done a week's fast whist working
and sometimes when I was living at home in the suburbs.
It has become easier over the years
basically because I KNOW what I'm doing,
I avoid a lot of contact with other people
largely because they don't get it & I can be a bit cranky or bedraggled.
Sometimes, particularly on fasts longer than 5 days,
possibly in starvation mode, I begin to feel reluctant to finish,
that food is an impurity, an imposition upon an enlightened corpus.
I understand these thoughts signify pleasure in liberation from material inputs
and cause me to idealize a death whereby I sit under a tree with sufficient water
to starve to death without being dehydrated
( many unofficial, doctor-supervise euthenasias
occur not just thru increasing doses of opiates
but thru withdrawl of water)
Starving to death with sufficient water would take longer
but wouldn't entail uncomfortable kidney failure.
In short, long experience of fasting
gives me great comfort & confidence in my ability to self-manage my being.
However, I have never been able to persuade even one person
to emulate the practice
so I accept that that my experience is unconvincing.
