The Goddess Bhadrakali is honored on the Fourth day of Bhaktapur Nawaraat (Nawaratri). On this day, worshippers travel to Yosinkhel to the Bhadrakali Temple. Due to its significant significance in the celebration of the Biska Jatra (Biska Jatra) Festival, the place is significant to the Newar community in Bhaktapur.

Yo:Sin Khel is located on the southern edge of Bhaktapur‘s central area. The Kaumari Temple, which is visited on the third day of Nawaraat (Nawaratri), is nearby and only a short distance away. A raised structure in the centre of the vast Yo:Sin Khel Square, where the Bhadrakali Ajima is located, is used to hoist the wooden pole known as the Yo:Sin Dyo during the Biska Jatra (Biska Jatra). The statue of the God Bhairav is kept in a small Polygonal Pati that is affixed to the building during the Biska Jatra (Biska Jatra) while the Yo:Sin is being raised.

In Nepalbhasa, Mata Bhadrakali is also known as Khusin Ajima in the direction of Bhaktapur, Lumri Ajima in the direction of Kathmandu in the direction of Bishnubi, Yappa Ajima in the direction of Patan, and Bishnu Bir in the direction of Madhyapur Thimi. Also known as Narayani or Narani. Bhawani Bhadrakali is thought to have been established on the fourth day of Nawaraat (Nawaratri). Bhadrakali Mata is the one who accepts Pleasant, Happiness, or Good Fortune in order to give it to her devotee.

Another name for Goddess Bhadrakali is Wife (Ardhangi) of Kashi Bishwanath(Mahadev). It used to be common in Nepal when there wasn’t a crown prince to wed a princess in order to succeed to the position. But the man or woman who wed that princess would pass away. When it was finally his turn to be poor, he was forced to wed the princess. At this point, Bhadrakali Ajima assumed the appearance of an elderly woman and offered counsel. A person who became a king by following Goddess  Bhadrakali’s counsel has been making pilgrimages to  Bhadrakali Ajima ever since. Originally known as Ajima Jatra, this Jatra is now known as Biska Jatra. Standing in the mentioned Ajima Jatra was Lhamaru Yosin Dyo. The practice of dragging a tiny chariot(Nakinju Khacha) is still practiced today . Currently, Bhadrakali‘s Chariot Yatra is another name for Ajima’s Jatra.

The Hanuman Ghat River, often referred to as the Hanumante River, originates in the vicinity of the Maheshwori Temple and flows directly over the Bhadrakali Temple to the east of Yosinkhel. The Chopinghat stretch of the river is frequented by the faithful of the Bhadrakali Temple.
