According to Hindu calendar, Goddess Chhinnamasta Jayanti is celebrated on Vaishakha Shukla Chaturdashi. Goddess Chhinnamasta is the sixth of the ten Mahavidya Goddesses and belongs to the Kali Kula. Goddess Chhinnamasta is the Shakti of Kabandha Shiva. Goddess Chhinnamasta is also popularly known as Goddess Prachanda Chandika. Goddess Chhinnamasta is depicted in a fierce and frightening form. That is why it is mainly practiced by Tantrics, Yogis and Aghoris. However, ordinary peoples can also worship Goddess Chhinnamasta to protect themselves from various kinds of calamities. According to Hindu scriptures, the Earth is constantly growing and destroying. At the time when the amount of growth increased and destruction starts to decrease, Goddess Bhuvaneshwari appears and at the time when destruction is high and growth is low, Goddess Chhinnamasta is in control.
According to Chhinnamasta Tantra Shastra, Lord Parshuram also worshipped Shri Chhinnamasta Vidya. Goddess Chhinnamasta is also worshiped by the Nath Panthi people. Guru Gorakhnath himself was also a worshipper of Goddess Chhinnamasta. Goddess Chhinnamasta is considered to be related to the Narashimha incarnation of Lord Vishnu.
The cultivation of Goddess Chhinnamasta is instructed only for qualified seekers. By worshiping Goddess Chhinnamasta, one is freed from the Jiva Bhava and attains the Shiva Bhava. Therefore, a person is detached from all kinds of worldly emotional bondage and experiences the supreme bliss of God. Goddess Chhinnamasta conveys the message of inward-looking cultivation. Her two companions are the form of Raja and Tama. Goddess Chhinnamasta is worshiped by followers of the Shakta, Buddhist, and Jain communities.
Hiranyakashyap and Vairochana were also worshipers of the goddess, hence the goddess is also worshiped as Vajra Vairochani.
Once upon a time, Goddess Parvati arrived to take a bath in the river Mandakini with Her two companions named Dakini (Jaya) and Varnini (Vijaya). After taking a bath, She became black under the influence of Kshudagni (hunger). At the same time, Jaya-Vijaya also prayed to Mata Parvati to provide food. Goddess Parvati asked the two companions to wait for some time. But after waiting for some time, Jaya-Vijaya, becoming hungry, again urged Maa Parvati to provide food and said, "Mother, give us food! You are the mother of the whole world, and the infant always asks mother for everything. That is why we are also begging for food to satisfy our hunger."
Maa Parvati said to them both, "I will arrange food for you as soon as you reach the home." Hearing the words of Maa Parvati, those companions named Dakini and Varnini pleaded with Goddess Maa and said in a sweet voice, "O Maa! Jagdamba! Mothers provide food immediately to their babies when they are hungry, we are becoming very restless due to hunger. Please grant us some food that can satisfy our hunger." Hearing the humble words of Her companions, Goddess Parvati immediately cut off her head with the tip of Her nail. The severed head of the goddess fell into Her left hand and three streams of blood began to flow from the torso. The goddess flowed two streams of blood towards Her companions, the goddess Herself began to drink the third stream with the severed head in Her left hand. The whole incident took place in a very secret manner and from that time onwards, she became known as Goddess Chhinnamasta in all the worlds.
