Consider the following statements of Sisupala from Mahbharatha.
O king, what can be done by me when (it seemeth) thou hast not heard anything before from virtuous old men giving lessons in morality? Hast thou never heard, O Bhishma, that reproach and glorification, both of self and others, are not practices of those that are respectable?
From the statements of Sisupala, it can be understood that glorifying others is a unrespectable act.
I am asking this question because Sisupala's statements cannot be treated as facts. Sisupala is saying that it has been told by virtuous old men. So, there are chances that scriptures may contain it.
Do any scripture (exactly) tells that glorifying others is a bad act among humans?
This question does not ask about glorifying gods or others divine beings.
