Kartik Purnima / Dev Diwali 2025: Mythology and Significance

The term “Tripurari”, which forms the basis of the name for this day, refers to a divine form of Lord Shiva who vanquished the powerful demon Tripurasura.

According to legend, Tripurasura, along with his brothers Vidyunmali, Tarakaksha, and Viryavana, had vanquished the gods and constructed three formidable cities in the sky, collectively called Tripura.

On Kartik Purnima, it is believed that Lord Shiva defeated these demons with a single arrow, leading to the illumination of the world—a reason this day is celebrated as a festival of lights, similar to Diwali but in honour of the deities.
