At night .. You must immediately sever its ties with elements of the earth ... at night you have to do is sleep or awake with all the limitations.
This problem of purity so humans back to the primeval
You may not eat in the form of tubers, rice, wheat, especially foods that have been cooked with fire
You should replace it with food that is in the air hanging fruit and should not be exposed to the fire .. like a bat
This is called the behavior of sky and earth, the behavior of the purity of day and night,
