Consider the following slokas from Ayodhya Kanda of Valmiki Ramayana.
Rama again and again saw that Kausalya, his mother who was crying thus, running after that chariot as though dancing, shouting"Oh, Rama, Rama!" "Oh, Seetha!" and "Oh, Lakshmana!" trickling tears descending from her eyes for the sake of Rama Lakshmana and Seetha.
Dasaratha exclaimed saying "Stop!" while Rama called out "Go on, proceed!" (In that way) Sumantra's mind became confused, as in between two (opposing) whirl pools.
Rama said to him: "You can say to the king that you did not hear (his call), even when scolded (later). seeing their grief for a long time is quite unbearbale."
The charioteer, doing as per Rama's words, took leave of those citizens and drive the horses more speedily even while they are going.
In normal perception, it is surely a lie. If not a lie, then, is there any scriptural justification regarding this?
