Everything visible goes to the remelt. A compressed formula embracing the whole field of vision: πάντα ὅσα ὁρᾷς — "all that you see" — TERMthe nature that governs the Whole will change "any moment now" (ὅσον οὔπω — "all but already"). It continues the wax of 7.23, but turned two iterations forward: out of the substance of present things — others, "and again others out of the substance of those" (πάλιν ἄλλα ἐκ τῆς ἐκείνων οὐσίας). The remelting is not an event but a conveyor with no final product; no form is terminal, including the one reading these lines. The unity of the raw material — the DOGMAοὐσία passing from form to form — is the same ground as in 7.9 ("one substance") and 7.10 (matter's return into the Whole).

ἵνα ἀεὶ νεαρὸς ᾖ ὁ κόσμος. The purposive ἵνα turns physics into teleology: nature destroys in order that — "that the world may be ever young." The perishing of forms is not entropy but the means of the whole's eternal youth: the cosmos does not age precisely because none of its things lingers. Hence the revaluation of loss: to grieve for what is swept away is to grieve that the world stays young. Cf. 4.36 (nature "loves nothing so much" as to change what is); 8.50 (the grape-cluster: unripe — ripe — raisin: all μεταβολαί); 12.23 (nature sets the timeliness of the end). The discipline is desire: consent to the remelting — one's own included.
