Constantly regard the universe as one living being, having one substance and one soul; and observe how all things have reference to one perception, the perception of this one living being; and how all things act with one movement; and how all things are the cooperating causes of all things which exist; observe too the continuous spinning of the thread and the contexture of the web.

Because most of what we say and do is not essential. If you can eliminate it, you'll have more time, and more tranquillity. Ask yourself at every moment, “Is this necessary?” But we need to eliminate unnecessary assumptions as well. To eliminate the unnecessary actions that follow. (Hays translation)

Πᾶν μοι συναρμόζει ὃ σοὶ εὐάρμοστόν ἐστιν, ὦ κόσμε· οὐδέν μοι πρόωρον οὐδὲ ὄψιμον ὃ σοὶ εὔκαιρον. πᾶν μοι καρπὸς ὃ φέρουσιν αἱ σαὶ ὧραι, ὦ φύσις· ἐκ σοῦ πάντα, ἐν σοὶ πάντα, εἰς σὲ πάντα. ἐκεῖνος μέν φησιν·

All that is harmony for you, my Universe, is in harmony with me as well. Nothing that comes at the right time for you is too early or too late for me. Everything is fruit to me that your seasons bring, Nature. All things come of you, have their being in you, and return to you.

Does anything genuinely beautiful need supplementing? No more than justice does—or truth, or kindness, or humility. Are any of those improved by being praised? Or damaged by contempt? Is an emerald suddenly flawed if no one admires it? Or gold, or ivory, or purple? Lyres? Knives? Flowers? Bushes? (Hays translation)
