For reason's measurements, which attain unto temporal things, do not attain unto things that are free from time-just as hearing does not attain unto whatever is not-audible, even though these things exist and are unattainable by hearing.

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.

Life and perfection, joy and repose and whatever all the senses desire, lie in the distinguishing spirit, and from it they have everything that they have. Even if the organs lose in power and the life in them decreases in activity, it does not decrease in the distinguishing spirit, from which they receive the same life, when the fault or infirmity is removed.

A line partakes of the simplicity of a point more than does a surface; and a surface [partakes thereof more] than does a material object-as was evident. From this consideration of a point and a material object elevate yourself unto a likeness of True Being and of the universe; and by means of [this] quite clear symbolism [of a point] make a conjecture about what has been said.

That that which is neither true nor truthlike does not exist. Now, whatever exists, exists otherwise in something else than it exists in itself.

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

In humility alone lies true greatness, and knowledge and wisdom are profitable only in so far as our lives are governed by them.
