“When one, for example, decides to stand on one leg for a day, one will surely feel very painful feelings. This pain is not some kamma-debt repayed but is quite natural, everybody will feel intense pains. We are not build to stand on one leg a whole day.
When i would tomorrow sport very fanaticly, i would surely have very painful feelings tomorrow because my body is not used anymore (once it was and i would not feel any pain) to this kind of activity. Is this kamma repayed? I think it is not sensible to decide this way.”
There are people with good genes who are less susceptible to physical abuse and trauma. Of course old age does affect our wellness. Also, the same contaminated food served to say, 200 diners…not everyone would get food poisoning. Isn’t hereditary good genes kamma vipaka?
