Passage 67

In English

Therefore, if the food has to be pure, then smoke must be the starting point, i.e., the flame. When trash is burnt, the polluted smoke percolates all the way to food. And when such food is consumed, diseases result. Contaminated food is thus responsible for most of the bad thoughts and actions one sees today. Seawater is salty but when it evaporates, the vapour is free from salt.
