Hey Pedro,
I'm missing something, somewhere.... I'm assuming you mean
grand expressions rather than
greater expressions, which don't appear in the text...
Grand Expressions are defined on pages 133 and 289:

... You may manifest one of any of the grand expressions granted by your psionic disciplines of 11th level once. At higher levels you receive access to more powerful grand expressions, but still may only manifest one each of any particular level. For example, at 16th level you may manifest one each of your 11th, 13th, and 15th level grand expressions. You regain all uses of the feature after a long rest.
I don't see any text there that lets me manifest a psionic
power using a grand expression, since they come from
disciplines.

By this text, a 16th-level Psion with a primary discipline of Psychoportation would manifest it's 11th-level
disintegrate and 15th-level
maze grand expressions as 5th-level spells (for the purposes of counterspell, etc.), because that's where manifesting level in the table maxes out.
If I'm reading this properly, there's no such thing as a "9th level expression". It would cap at 5th, available at
psion level 9.
So, I'm back to my original question: Should
Burst read "5th level expression" rather than "9th level expression"?
The follow up is: are there errata changes to the way grand expressions are defined in the book, to either change the manifested-spell-level to match the actual-spell-level, or to allow psionic powers to be manifested using those "slots"?
Thanks!
James
