According to the Purnimanta Hindu Panchang, Kubjika Jayanti is observed on the Krishna Paksha Trayodashi Tithi of the Vaishakha month. In the Amanta Panchang, this Tithi falls during the Krishna Paksha of the Chaitra month. Kubjika Jayanti is a festival dedicated to Goddess Kubjika. In Hinduism, Goddess Kubjika is worshipped as one of the Dwadasha Siddhividya Goddesses.
Within the Shakta Sampradaya, Kubjikamat and Kaula Tantra, the worship of Goddess Kubjika holds special significance. She is also known by the names Vakreshwari, Vakrika and Chhinnini. The word Kubjika originates from Sanskrit and means "bent" or "curved."
Once, Lord Shiva embraced His divine consort Vakrika. Out of modesty, the Goddess bent Her body slightly to one side. Because of this divine act, She came to be known as Kubjika or Vakrika. According to the commentary of the Shatasahasra Samhita, the Goddess who, being bent, pervades all space in a contracted form is called Kubjika.
References to Goddess Kubjika are found in the Agni Purana, Matsya Purana and Garuda Purana, which were compiled between the 5th century and the early 9th century CE, during the Gupta period. From the 10th to the 12th century, the worship of Goddess Kubjika flourished in North India, reaching its peak, but gradually became obscure by the end of the 15th to 16th centuries.
In Nepal, evidence of the worship of Goddess Kubjika is found between 900 and 1600 CE. Manuscripts of texts such as the Manthana Bhairava Tantra, Shatasahasra Samhita, Kubjikamata Tantra, Amba Samhita and Shrimata Tantra have been discovered there. Even today, the Pashchimamnaya Kubjikakrama tradition continues to be practiced in Nepal.
