Today is the ninth day of Shardiya Navratri. On the ninth day of Navratri, the ninth power of Maa Durga is worshipped. The name of the ninth and supernatural power of Maa Durga is Siddhidatri. It is said that by worshiping Maa Siddhidatri, a person gets all kinds of siddhis. According to Markandeya Purana, there are a total of eight siddhis, namely Anima, Mahima, Garima, Laghima, Prapti, Prakamya, Ishitva, and Vashitva, which can be easily obtained by worshiping Maa Siddhidatri. According to Dev Purana, Lord Shiva also attained siddhis by the grace of Maa Siddhidatri, and by her grace Lord Shiva was called Ardhanarishwar. Therefore, on this day, Siddhidatri must be worshipped to attain special siddhis.
