Navaratri is celebrated five times a year. They are Vasanta Navaratri, Ashadha Navaratri, the Sharad Navaratri, and the Paush/Magha Navaratri. Of these, the Sharad Navaratri of the month of Puratashi and the Vasanta Navaratri of the Vasanta kala are the most important.
This is celebrated during Vasanta Rhitu (beginning of summer) (March- April). This is also known as Chaitra navarathri as it falls during the lunar month of Chaitra.
In days long gone by, King Dooshibago was killed by a lion when he went out hunting. Preparations were made to crown the prince Sudarsana. But, King Yudhajit of Ujjain, the father of Queen Lilavati, and King Virasena of Kalinga, the father of Queen Manorama, were each desirous of securing the Kosala throne for their respective grandsons. They fought with each other. King Virasena was killed in the battle. Manorama fled to the forest with Prince Sudarsana and a eunuch. They took refuge in the hermitage of Rishi Bharadwaja.
The victor, King Yudhajit, thereupon crowned his grandson, Satrujit, at Ayodhya, the capital of Kosala. He then went out in search of Manorama and her son. The Rishi said that he would not give up those who had sought protection under him. Yudhajit became furious. He wanted to attack the Rishi. But, his minister told him about the truth of the Rishi’s statement. Yudhajit returned to his capital.
Fortune smiled on Prince Sudarsana. A hermit’s son came one day and called the eunuch by his Sanskrit name Kleeba. The prince caught the first syllable Kli and began to pronounce it as Kleem. This syllable happened to be a powerful, sacred Mantra. It is the Bija Akshara (root syllable) of the Divine Mother. The Prince obtained peace of mind and the Grace of the Divine Mother by the repeated utterance of this syllable. Devi appeared to him, blessed him and granted him divine weapons and an inexhaustible quiver.
The emissaries of the king of Benares passed through the Ashram of the Rishi and, when they saw the noble prince Sudarsana, they recommended him to Princess Sashikala, the daughter of the king of Benares.
The ceremony at which the princess was to choose her spouse was arranged. Sashikala at once chose Sudarsana. They were duly wedded. King Yudhajit, who had been present at the function, began to fight with the king of Benares. Devis helped Sudarsana and his father-in-law. Yudhajit mocked Her, upon which Devi promptly reduced Yudhajit and his army to ashes.
Thus Sudarsana, with his wife and his father-in-law, praised Devi. She was highly pleased and ordered them to worship her with havan and other means during the Vasanta Navarathri. Then she disappeared.
Prince Sudarsana and Sashikala returned to the Ashram of Rishi Bharadwaja. The great Rishi blessed them and crowned Sudarsana as the king of Kosala. Sudarsana and Sashikala and the king of Benares implicitly carried out the commands of the Divine Mother and performed worship in a splendid manner during the Vasanta Navarathri.
Sudarsana’s descendants Sri Rama and Lakshmana also performed worship of Devi during the Sharad Navarathri and were blessed with Her assistance in the recovery of Sita.
According to the Krittibas Ramayana, Rama invoked the goddess Durga in his epic battle against Ravana. Although Goddess Durga was traditionally worshipped in the late spring, due to contingencies of battle, Lord Rama had to invoke her in the form of astam (eighth) Mahavidya (Maa Bagla) in the autumn and thus is known as akaal bodhan (invoking out of scheduled time). This autumnal ritual was different from the conventional Durga Puja, which is usually celebrated in the springtime. So, this Puja is also known as 'akal-bodhan' or out-of-season ('akal') worship ('bodhan'). This Rama's date for the Navratra puja has now gained ascendancy and culminates with Dusherra in North India on the following day
