I forgot to mention this in class when we were talking about the Ramayana.
You may have recalled me talking about Shesha, the companion naga (snake) of Vishnu. What I forgot to mention was that when Vishnu decides to send an avatar to earth, there is always an avatar of Shesha sent to assist the Vishnu avatar in whatever task needs to be done to maintain balance. In the Ramayana, Rama is told by the Gods that he is an avatar of Vishnu. This means that there is also an avatar of Shesha around. That avatar is Laksmana, the brother who decided to leave his home and his family to stay with Rama in his exile, who fought along with Rama against demons, and who aided Rama in his rescue of Sita.
I apologize that I forgot to mention this in class, as I feel it is an important point.
