The Acintita Sutta.

Four sorts of contemplations that lead in endless and vexing loops of thought are described here. The origin of the world is one, and with it we get a sense of both how and why these contemplations lead on ad nauseum. Another has to do with the precise way that kamma works.

The other two are related, having to with the impossibility of delineating the range of powers of either a Buddha or a person in jhana. In this sense, it is only when 'experiencing jhana' that nothing can be said of citta. Much can usefully be said about the normal unlearned mind, make no mistake.
