Room from a change of scale. The advice comes in two beats. First, a therapy of judgement: "you can remove much of the superfluous (περισσά) that troubles you — it TERMlies wholly in your opinion" (cf. 9.13 — trouble is "within, in the ὑπολήψεις"; DOGMAthe trouble is in the judgement, not the thing). Second, how to remove it: to gain "ample room" (εὐρυχωρία) by EXERCISEtaking in with the mind the whole cosmos and all eternity — the spatial-and-temporal view from above.

The swiftness of change. The addition: the TERM"rapid change" (ταχεῖα μεταβολή) of each particular thing — brief the span from birth to dissolution, and before and after, an abyss (ἀχανές, ἄπειρον). Against eternity the "troubling" shrinks to nothing. EXERCISEThe contemplation of nature here works as a clearing of space in the soul. The governing discipline is assent.
