Genre and place in the book. The third "death" fragment of the book (after 04-05 "death is a mystery of nature" and 04-09 on the good of the Whole), and the most physical: what happens to you in death at the level of cosmic ontology.
You are a part. Ἐνυπέστης ὡς DOGMAμέρος — "you have existed as a part": not a self-standing whole, but a member of a single Whole (the DOGMAunity-of-cosmos card says it directly: each is a μέρος of a single body). From this status follows the part's destiny — to return into the Whole.
Reabsorption: a crucial correction. "ἐναφανισθήσῃ τῷ γεννήσαντι" — you will disappear into what produced you; but "μᾶλλον δὲ" ("or rather") introduces a correction: not merely "vanish," but be received back (ἀναληφθήσῃ) into its TERMseminal reason (λόγος σπερματικός) by TERMtransformation. The correction removes the shade of annihilation: death is not ἀφανισμός as disappearance, but a DOGMAreturn to the source, a recasting. The seminal reason is the Stoic generative principle: the λόγοι σπερματικοί are the "seeds" of things in the cosmic Logos, from which all is born and into which it returns (DL 7.135–136).
κατὰ μεταβολήν — by transformation. TERMTransformation is the very mode of the cosmos's existence; death is merely a particular case of it (cf. 04-05: the σύγκρισις/λύσις of the same elements). Nothing perishes; everything passes over.
The twin, 6.24. Alexander the Macedonian and his groom were alike "received into the same seminal principles of the universe — or alike dispersed into atoms": death levels all, and under either of the two cosmologies (providence or atoms) complaint is senseless.
The disciplines. The principal one is desire: the acceptance of one's own dissolution as a return into the source. The secondary is assent: the physical doctrine of the part and its reabsorption, to be taken up as true.
Parallels. Return into the seminal reason by transformation — Med. 4.21; 8.18; 6.24; 04-05. You are a part of the Whole, returning into it — 04-09; Med. 10.6 (see DOGMAunity-of-cosmos). The seminal reason (λόγος σπερματικός) — DL 7.135–136 (see TERMlogos). Transformation as the mode of the cosmos — Med. 2.3; 9.19 (see TERMmetabole).
