Inedia (Latin for "fasting") or breatharianism is the belief that it is possible for a person to live without consuming food. Breatharians claim that food, and in some cases water, are not necessary for survival, and that humans can be sustained solely by prana, the vital life force in Hinduism. According to Ayurveda, sunlight is one of the main sources of prana, and some practitioners believe that it is possible for a person to survive on sunlight alone. The terms breatharianism or inedia may also refer to this philosophy when it is practiced as a lifestyle in place of the usual diet.
Breatharianism is deadly in practice, and several adherents of these practices have died from starvation and dehydration. Though it is common knowledge that animals require sustenance to survive, breatharianism continues.
Or is that merely another form of self-abuse ??
Speaking personally - I enjoy eating; it is a pleasure that can usually be depended upon & which is able to bring great satisfaction if/when one is also health oriented.
Not against the consumption of bugs either, as that would make them useful rather than mostly annoying, but:
If they are more costly to use instead of common market items like bean sprouts or mushrooms, why bother ??
Yes, life is meaningless with or without food, but it's much more meaningless without eating food. And breathing is good for one and keeps one alive, and it can be done without thinking about it, until something goes amiss. Crickets, meat, fish, plants, sunlight, oxygen---it's all good.
