Preserve, within a wild sanctuary

Good morning!

I hope this musing finds you well.  And that you've had some time over this past Easter weekend to do something you enjoyed.

... It may be that all one needs to write is some inspiration from the voices waiting inside Bartlett's Familiar Quotations (my copy being the 1955 edition, by coincidence, the year I was born).

Hoping for some concrete ideas about the word "sanctuary" I turned to the only quotation indexed to that word:

Preserve, within a wild sanctuary, an inaccessible valley of reveries.

from a Certain Measure (1943)

by Ellen Glasgow (1874-1945)

Not even sure what it means!  Why can she not get to the reveries - the dreams?

But there's a sensibility I like.

She's instructing us to keep those (as yet?) dreams safe, inside a wild sanctuary.

Implying that our dreams are wild?  That our dreams are fresh, new, unexplored ... not everyday and overused?

Thinking this much about a single line ... it's rather like figuring out poetry, which I admit I've never like to do.  Perhaps I'm finally old enough to tackle poetry?  It's been rather fun this morning thinking on Glasgow's words.

Best regards,

Why's Woman
