The following text is adapted from Amy Lowell's 1912 poem "Summer."

It is summer, glorious, deep-toned summer,
The very crown of nature's changing year
When all her surging life is at its full.
To me alone it is a time of pause,
A void and silent space between two worlds,
When inspiration lags, and feeling sleeps,
Gathering strength for efforts yet to come.

As used in the text, what does the phrase "a void" most nearly mean?
