Rama is remembered as Maryada Purushottam, the person who lived within the limits of righteousness (dharma) in every role: as a son, brother, husband, friend and king. Ram Navami is a day to reflect on those values, not only to celebrate a birth.
The festival is observed with fasting, reading of the Ramayana or Ramcharitmanas, singing bhajans and a short birth ceremony at midday, when an image of baby Rama is placed in a cradle and rocked. Temples across India hold processions and the wedding of Sita and Rama is celebrated in many places.
Ending the nine nights of Chaitra Navratri, Ram Navami also brings together the worship of the Divine Mother and of Rama. In many North Indian homes, young girls are worshipped and fed (kanya pujan) on this day to conclude the Navratri fast.
King Dasharatha of Ayodhya had three queens but no children. On the advice of his guru Vasishtha, he performed a sacrifice for progeny (Putrakameshti yajna) led by the sage Rishyashringa. From the fire emerged a divine figure with a bowl of sweet rice pudding (payasam), which the king shared among his queens, Kausalya, Kaikeyi and Sumitra.
In due time, on the ninth day of the bright half of Chaitra, at midday, Kausalya gave birth to Rama. Kaikeyi gave birth to Bharata, and Sumitra to the twins Lakshmana and Shatrughna. The Ramayana describes the moment as one when the whole of nature was peaceful and pleasant, and Ayodhya celebrated with music and festivity.
