When Hanuman entered Lanka as Rama’s ambassador and spoke to Sita, Ravana came to know of this and he ordered that Hanuman be punished. This is quite contrary to the accepted code of conduct of a king. To kill an ambassador or to punish one who has come as a messenger on behalf of the someone else is not the right code of conduct for a king of the country. Vibhishana tried to explain to Ravana this principle by which he should not punish one who has brought a message and Vibhishana tried to get Hanuman released. (SSB 1977, pp. 115-116)
