Legend of Ramalakshmana Dwadashi
It is believed that in the times of Treta yuga, the ruler of Ayodhya, King Dasaratha observed the Ramalakshmana Dwadashi to pray for a son. King Dasaratha’s prayers were answered as Lord Rama was born to him in the next year on the auspicious day of the Chaitra Masa Navami, which according to Gregorian calendar falls in the month of April or May.
On this day, some devotees keep a stringent fast to pray for a son and to attain moksha or salvation. Sri Rama puja is carried out on this day with Shodasopachara. Devotees visit the nearby Vishnu temples to take part in the puja proceedings.
Ramalakshmana Dwadashi is also observed as Champaka Dwadashi in some parts of the country, as Odisha. It is an important festival, which is celebrated in the Jagannath Temple of Puri. It is an auspicious day and an important festival for the Utkala Brahmins and is celebrated as such with special puja and bhogs dedicated to Lord Jagannath.
