Makara Sankranti identifies a period of enlightenment, peace, prosperity and happiness followed by a period of darkness, ignorance and viciousness with immense sorrow. The six months of northern movement of the sun is followed by six months of southern movement. This is the same analogy as the Kingdom of Rama that lasts for half the world cycle followed by the Kingdom of Ravana for the other half of the cycle. Analogously, the kingdom of Rama is heaven and the kingdom of Ravana is hell.
