According to that which is said above in the third chapter of this treatise, in order to understand well the first part of the Song I comment on, it is requisite to discourse of those Heavens, and of their Movers; and in the three preceding chapters this has been discussed.

I say, then, to those whom I proved to be Movers of the Heaven of Venus: "Ye who, with thought intent" (_i.e._, with the intellect alone, as is said above), "the third Heaven move, Hear reasoning that is within my heart;" and I do not say "Hear" because they hear any sound, for they have no sense of hearing; but I say "Hear," meaning with that hearing which they have, which is of the understanding through the intellect.

I say, "Hear reasoning that is within my heart," within me, which as yet has not appeared externally.
It is to be known that throughout this Song, according to the one sense (the Literal), and the other sense (the Allegorical), the Heart is concerned with the secret within, and not any other special part of the soul or body.

When I have called them to hear that which I wish to say, I assign two reasons why I ought fitly to speak to them.

One is the novelty of my condition, which, from not having been experienced by other men, would not be so understood by them as by those who superintend such effects in their operation.
