For finding sunrise and sunset timings of your city
What is the Tivihar?
In tivihar one does not take food of any kind including liquids except water after the sunset until the sunrise next day but can take water.
What is the Chauvihar?
Chauvihar means one does not take any food or any liquids after the sunset until the sunrise next day.
Don’t eat or drink untill 48 minutes after sunrise, then recite Navkar 3 times and
break the fast. By doing navkarsi one day, a person can shed karmas
equivalent to 100 years of torture in hell – i.e. karma nirjara.
You break fast more than 3 hours after sunrise. Karma nirjara equivalent to
1,000 years of hell life.
You break fast 4½ hrs after sunrise. Karma nirjara – 10,000 years of hell life.
Break fast exactly after ½ day passes = 100,000 years of karma nirjara from hell
When only ¼ of the day remaines, break the fast.
Eat only once, sitting at one place for less than 48 minutes. Also drink cooled
boiled water, up to sunset. 1 million years equivalent karma nirjara.
Eat only in one sitting, eat special fried food and things made out of yogurt.
Karm nirja =10 million years
One meal without any vigai (10 billion years of karma nirjara)
Means fasting, partial or complete, for a pre determined time.
