Swami Vishwananda told us 2009: "Durga's ninth mold is the form of "Siddhidatri". She delivers success. According to "Markendeo Puran" there are eight types of success, such as "Anima", "Laghima", "Prapti", "Prakashya", "Mahima", "Ishhattya", "Bashittya", "Sarvakaam bashayita" and "Sarvagyata". But in the "Sri Krishna Janmakhanda" of the "Brahmavaivarta Puran", there are another ten types of success such as "Doorsravan", "Parakayaprabeshan", "Baksiddhi", "Kalpavrikshattwa", "Srishti", "Samharkaransamartha", "Amarattwa", "Sarvanaykattwa", "Bhavna" and "Siddhi". Thus there are eighteen types of successes. Mother Siddhidatri is capable of rendering all these forms of successes to her devotees. According to the Purans, Lord Shiva achieved salvation by the grace of this deity. The deity is seen sometimes sitting on a lotus and sometimes mounted on a lion. She is four armed. The lower right hand of the Goddess holds a disc and the upper right hand holds a club. The lower left hand holds a conch shell and the upper hand holds a lotus. She is worshipped on the ninth day of the Durga puja. She is the ultimate form of the Goddess among the Navadurga. After having performed the worship of the other forms of the Goddess according to the rituals mentioned in the Sashtra, the devotee can then start the worship of this deity. Those who worship the Goddess with full devotion are bestowed with all the success. She has been unified with the forces of sustenance and salvation of the great Lord Vishnu".
