1. They need sun
2. They need to breath
3.I have no idea if they susttain physicality even
Think about that #3 question
If someone is vibrating at a level to ingest sun through the pineal gland and they are living on sunlight and breath
I'd say sustaining physical activity would be rather easy for them, but everyone goes through stages of development....Do they even s tay in the physical very much is the first question I would ask?
They are a saint if one believes in saints and miracles
Or a guru
or a sneak and a liar
