Kartika Poornima (Kartika purnima) is a Hindu, Jain and Sikh holy festival, celebrated on the Purnima (full moon) day or the fifteenth lunar day of Kartika (November–December). It is also known as Tripuri Poornima and Tripurari Poornima. It is sometimes called Deva-Diwali or Deva-Deepawali – the festival of lights of the gods.

Tripuri Poornima or Tripurari Poornima derives its name from Tripurari – the foe of the demon Tripurasura. In some legends of Kartik Poornima, the term is used to denote the three demon sons of Tarakasur. Tripurari is an epithet of god Shiva. Shiva in his form as Tripurantaka (“Killer of Tripurasura”) killed Tripurasura on this day.Tripurasura had conquered the whole world and defeated the gods and also created three cities in space, together called “Tripura”. The killing of the demon(s) and destruction of his/their cities with a single arrow – by Shiva overjoyed the gods and they declared the day as a festival of illuminations. This day is also called “Dev-Diwali” – the Diwali of the gods. Diwali is the Hindu festival of lights.

Kartik poornima is also the birthday of Matsya, god Vishnu’s fish-incarnation (Avatar). It is also the birthday of Vrinda, the personification of the Tulsi plant and of Kartikeya, the god of war and son of Shiva. This day also is considered special for Radha, the lover of Krishna – Vishnu’s incarnation. It is believed that Krishna and Radha danced rasa and Krishna worshipped Radha on this day. This day is also dedicated to the pitrs, dead ancestors.

Underhill believes that the origins of this festival may lie in ancient times, when a sacrifice called Shakamedhah was performed to attain victory over enemies.

The festival has even more significance when the day falls in the nakshatra (lunar mansion) Krittika and is then called Maha Kartik. The nakshatra is Bharani, the results are stated to be special. If it is Rohini nakshatra, then the fruitful results are even much more. Any philanthropic act on this day is supposed to bring benefits and blessings equal to the performing of ten yajnas (sacrifices).
