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

The line urges the cultivation of an inner refuge—an imaginative, private “valley” protected from intrusion—where one’s capacity for reverie, hope, and creative vision can survive the pressures of practicality and social demands. “Wild sanctuary” suggests something untamed and self-renewing rather than orderly or publicly curated; “inaccessible” implies deliberate boundaries, a chosen privacy. Read this way, the quote values interior life as a form of preservation: not escapism so much as a necessary reserve of feeling and imagination that sustains resilience, artistic perception, and moral independence when the outer world becomes constraining or disillusioning.
