I just remembered hearing somebody say once (or did I read it...) that the
suffusing stage actually happens aften you come out of the jhana, not while
you are in it, since there is said to be no five-sense experience in the
jhana. But then again, different people have different oppinons about what
jhana actually is, etc. (Ajahn Maha Boowa just uses the word samadhi for
this reason - the more samadhi, the better).
