We all know about Sita’s abduction by Ravana, but what is not so well known is that Sita was abducted once earlier in the epic too. This incident was used as an act of foreshadowing, which is an important narrative device in epics and plays.
In the aranya kanda, i.e. soon after Rama, Sita and Lakhsman left Ayodhya, the three of them come across a demon in the forest of Dandaka. He had a huge face, a horrible belly and quite a horrifying appearance. He made himself even more grotesque, clad in a tiger skin, with blood smeared all around and fat hanging from the skin. He had a spear, with animal heads pierced on them.
