Medhātithi’s commentary (manubhāṣya):
This is a statement commendatory of what has been enjoined in the foregoing verses. Hence it has to be explained as follows:—

‘Through cenmre’;—i.e., by listening to the censuring of his Teacher—‘one becomes an ass’; the ablative being taken either as denoting cause, or as having the force of the participle; parīvādāt being construed as ‘parīvādam śrutvā,’ ‘having listened to censuring.’

‘Defamer,’—the person listening to defamation is figuratively called ‘defamer just as one preparing meat has been called the ‘Killer’ of the animal. As for the act of defaming itself, the prohibition of this becomes naturally implied by the prohibition of hearing it.

‘One who lives upon’;—he who supports himself on what he receives from his Teacher; or one who behaves ill-mannerly towards him.

‘One who is jealous’;—who does not brook the rise and advancement of his Teacher and burns within (at its sight).

The two latter have not been spoken of before this; hence what is said in regard to these is to be regarded as direct injunction.

‘Parīvāda’ and ‘parivāda,’ both forms—with long as well as with the short ī—are correct, according to Pāṇini, 6.3.122.—(201)
