In creating the world, God used arithmetic, geometry, and likewise astronomy.

An external thing that is knowable [is knowable] by means of something internal that is consubstantial [with the rational soul].

For all the [body's] members seek nothing except inseparable union with the intellect, as with their beginning, ultimate good, and everlasting life.

Love is subsequent to knowledge and to the thing known, for nothing unknown is loved.

God says to man: 'Be thou thyself, and I shall be thine.'

There are not many beginnings but there is a single Beginning, prior to multitude. But if you were to say that the beginnings are plural apart from their partaking of the One, that statement would self-destruct. For, surely, these plural beginnings would be both alike, by virtue of their not partaking of the One, and not alike, by virtue of their not partaking of the One.

Through itself the soul arrives at all harmony that is perceptible in otherness-just as through what is internal the soul arrives at what is external.
