2.38

Regarding "that which burns and that which is weighed are disputed": "disputed" means controversy; that which burns and that which is weighed have two different interpretations, hence termed disputed. That is, some say: the essential nature of that which burns and that which is weighed is also as before, only the four external dhātus. Or again, others say: only the fire-dhātu can be called that which burns, and that which is weighed is only heaviness; heaviness is derived matter, the heavy tangible among tangibles.
