Genre and place in the book. The maxim points to the single place where the Stoic may seek joy and rest: continuous social action, carried out with the remembrance of God. Thus the discipline of action (κοινωνικαὶ πράξεις) is fused with a theological frame (μνήμη θεοῦ). The passage returns to the governing theme of Book V (05-01, 05-16): the "work of a human being" is social work.

Joy and rest — in one thing (Ἑνὶ τέρπου καὶ προσαναπαύου). Two verbs — "take joy" (τέρπου) and "repose, take rest" (προσαναπαύου) — place both pleasure and repose in a single thing. The Stoic finds happiness not in the external but in the activity of virtue; here it is specified as social action. It is in that action — and not in leisure away from it — that the soul finds its rest.

From act to act (πρᾶξις κοινωνική). "To pass from one TERMsocial act to another" — a continuous chain of κοινωνικαὶ πράξεις. Τὸ κοινωνικόν is the defining feature of rational nature: to be rational is to be social, and the proper "work of a human being" (ἀνθρώπου ἔργον) is action for the common good. Behind it lies DOGMAoikeiōsis: the natural "appropriation" that widens from oneself to fellow-citizens and to all rational beings. Cf. 05-16 (the good of a rational being lies in κοινωνία).

With the remembrance of God (σὺν μνήμῃ θεοῦ). The theological seal on the action: every social act is done "with the memory of God." This is not mere philanthropy but action referred to the divine — whether to the god of the cosmos or to the "god within" (δαίμων) — like the man who is "a priest and minister of the gods, using the deity planted within him" (03-04). Thus the discipline of action joins the discipline of desire: social work turns out to be at once a service to the Whole and, for that reason, a source of unshakeable joy.

Disciplines and parallels. The principal one is action (the continuous κοινωνικαὶ πράξεις); the secondary is desire (joy and rest referred to God and placed in this work alone). Parallels: 05-16 (the good of a rational being is fellowship); 05-06 (ἔργον κοινωνικόν); Med. 2.1 (born for cooperation); 03-04 (priest and minister of the god within). The ground is DOGMAoikeiōsis and the social nature of the human being; LS 57.
