Splashing in the bath

Many, many years ago, before the age of the Internet which reveals all secrets, I found a "motto" in my Christmas cracker, which read

"And what a romp they had!
The bathroom was drenched with their splashings.
Of such is the Kingdom of Heaven"


I carried this enigmatic motto in my wallet for ages, and one day discovered that they were the last lines of a novel by Aldous Huxley, "Point Counter Point" (1928).
