Apparently the technical term is racing thoughts, but here's a clip from CTILibrary.com: "Finally, if you're cursed with a runaway mind, remember, as Oswald Chambers said, "God . . . loves me, and I will never think of anything that he will forget, so why should I worry?"

This will get your thoughts racing, from NYT's review of Harold Bloom's latest:

Yet the title of Bloom's antiphilosophical book, ''Where
Shall Wisdom Be Found?,'' is, of course, an ancient
philosophical question. He never stoops to say in a
reductive way what wisdom finally is, but he does give us
some of its characteristics. He speaks of the ''wisdom of
annihilation'' in Ecclesiastes, of the ''structure of
gathering self-awareness'' in Job and ''King Lear,'' of
how, from Homer, we learn the hard truth that ''the gods
are selfish, nasty spectators, all too happy to see us
suffering in their theater of cruelty.'' Yet human
suffering can be made bearable: ''Wisdom literature teaches
us to accept natural limits.''
