But God himself in his essence is thinking, and He is thinking and only that, and himself according to his thinking is essence, all of Him essence and only that, above essence all of him and above thinking all of him, because He is also indivisibly one, partless and simple. Therefore, whoever in whatever has thinking, has not yet left the dyad, but whoever abandonded thinking perfectly has become totally into the one, having left aside excellently the power of thinking.

ἀλλ᾿ αὐτὸς κατ᾿ οὐσίαν νόησίς ἐστιν ὁ Θεός· καὶ ὅλος νόησις καὶ μόνον· καὶ αὐτὸς κατὰ τὴν νόησιν οὐσία καὶ ὅλος οὐσία καὶ μόνον· καὶ ὑπὲρ οὐσίαν ὅλος καὶ ὑπέρ νόησιν ὅλος, διότι καὶ μονὰς ἀδιαίρετος καὶ ἀμερὴς καὶ ἁπλῆ. Ὁ τοίνυν καθ᾿ ὁτιοῦν νόησιν ἔχων, οὔπω τῆς δυάδος ἐξῆλθεν· ὁ δὲ ταύτην πάμπαν ἀπολιπών, γέγονε ποσῶς ἐν τῇ μονάδι, τὴν τοῦ νοεῖν ὑπεροχικῶς ἀποθέμενος δύναμιν.
