A fear taken apart by questions. Seven rhetorical questions in a row — and not a single assertion: the passage cures the fear of TERMchange by pure maieutics. First move — ontological: "what can come to be without change?" Every birth of anything is something's μεταβολή; to fear change is to fear the very condition of existence. Second move — theological: change is not merely tolerable to TERMthe nature of the Whole — it is what is "dearest and most proper" to it (φίλτερον ἢ οἰκειότερον). The direct parallel is 4.36: "the nature of the Whole loves nothing so much as to change the things that are"; cf. 8.6.
The bath and the meal. Two homely examples bring the pathos down to the kitchen and the boiler-room: the hot bath exists because the firewood stops being firewood; nourishment — because the food stops being food. Everything useful (τὰ χρήσιμα) is accomplished at the price of something's μεταβολή. The argumentative trap snaps shut in the last question: "and your own changing (αὐτὸ τὸ σὲ μεταβαλεῖν) is just like these, and just as necessary to the nature of the Whole." The word "death" is never uttered — yet it is precisely death that is normalized here: in the economy of the cosmos you are the same firewood, the same bread; your transformation warms someone and feeds someone. A quiet meditation on death without funerary vocabulary.
Stoic physics behind the scenes. Behind the examples stands the doctrine that the elements live each other's death and the Whole renews itself by the mutual transformations of its parts (cf. 04-46 — Heraclitus's "the death of earth is the birth of water"; 06-15 — the river of becoming). The discipline is desire: to accept μεταβολή as the law under which you yourself stand.
