Interesting to see water-fasting here. :)
I come from Jainism. A practice where we apply certain things in life to achive non-violence, detachment, and a spiritual life.
One of the them I saw my grandmother doing was fasting.
It includes three things:
- Do not eat
- Do not drink
- Do not talk
Glad to see you are doing this for 3 days, though we generally do it for half a day. Plus, back in those days, we were never eating after the sunset. (6 PM)
And that was considered fasting. An everyday affair for my grandmother.
It is done to purify not just body but also soul. Lots of stuff on the web around this. Will link to one: https://en.wikipedia.org/wiki/Fasting_in_Jainism
