For what are the forms by means of which a man may reveal his thoughts?
Are they not those of nature? But although he is created in the closest
sympathy with these forms, yet even these forms are not born in his
mind. What springs there is the perception that this or that form is
already an expression of this or that phase of thought or of feeling.
For the world around him is an outward figuration of the condition of
his mind; an inexhaustible storehouse of forms whence he may choose
exponents--the crystal pitchers that shall protect his thought and not
need to be broken that the light may break forth. The meanings are in
those forms already, else they could be no garment of unveiling. God has
made the world that it should thus serve his creature, developing in the
service that imagination whose necessity it meets. The man has but to
light the lamp within the form: his imagination is the light, it is not
the form. Straightway the shining thought makes the form visible, and
becomes itself visible through the form. [Footnote: We would not be
understood to say that the man works consciously even in this.
Oftentimes, if not always, the vision arises in the mind, thought and
form together.]

In illustration of what we mean, take a passage from the poet Shelley.

In his poem _Adonais_, written upon the death of Keats, representing
death as the revealer of secrets, he says:--

"The one remains; the many change and pass;
Heaven's light for ever shines; earth's shadows fly;
Life, like a dome of many coloured glass,
Stains the white radiance of eternity,
Until death tramples it to fragments."
