俱舍論記 13.157

13.157

「有覆無記表至矯自歎等」者，釋第五句，簡差別也。有覆無記表欲界定無，唯在初定。「曾聞」已下，引證。誑諂發言顯有語表，引出眾外顯有身表。

Regarding "Concealed-unspecified manifestation... deceitfully praising oneself, and so forth": this explains the fifth line, distinguishing the difference. Concealed-unspecified manifestation definitely does not exist in the Desire Realm; it exists only in the first dhyāna. From "It is heard that" onward, it cites evidence. Speaking deceitfully and flatteringly shows that there is vocal manifestation; leading [someone] out of the assembly shows that there is bodily manifestation.
