On last day of navaratri, Sri Kanaka Durga Devi will be adorned as Sri Rajarajeswari Devi.
On Dasami, she sits on the throne holding ‘Ikshu khanda’ (sugarcane) in one hand and giving blessings to devotees with the other in ‘abhaya mudra’ (no fear). Sweet Juice of Sugarcane symbolizes the juice of bliss (atma gnana – the self realisation). She whips those who are wicked and arrogant or harmful to others. Her peaceful, smiling, benevolent looks mesmerizes the devotees.
She killed and defeated many demons in many kalpas, hence, is known as Aparajitha Devi, one who cannot be defeated.
Rajarajeswari Devi is gnana swaroopini (the embodiment of Gnana or wisdom). The Trimurthis - Brahma, Vishnu and Maheswara are the lords of Ashta Digpalakas. They are called Rajeswar, and the goddess who rules over these Trimurthis is called Rajarajeswari.
She wears beautiful diamond chains, broad ear rings, jewels on the shoulders made of diamonds and other costly stones as she is alankara priya. They are also symbol of prosperity.
She is adhisthana devatha (presiding deity) of Sri Chakra. Where does she live? Sri Manmanidweepa Sri Nagara sthitha chintamani griha is her residence. She lives there along with all parivara devatha and making mahakameswara’s anka as nilaya.
