In Hindu mythology, Daksha-Yajna(m) (Daksha-Yagna(m)) or Daksha-Yaga is an important event, which is narrated in various Hindu scriptures. It refers to a yajna (sacrifice) organized by Daksha, where his daughter Sati immolated herself. The wrath of god Shiva, Sati's husband, thereafter destroyed the sacrifice. The tale is also called Daksha-Yajna-Nasha ("destruction of Daksha's sacrifice). The story forms the basis of the establishment of the Shakti Peethas, temples of the Hindu Divine Mother. It is also becomes a prelude to the story of Parvati, Sati's reincarnation who later marries Shiva.
The mythology is mainly told in the Vayu Purana. It is also mentioned in the Kasi Kanda of the Skanda Purana, the Kurma Purana, Harivamsa Purana and Padma Purana. Linga Purana, Shiva Purana, and Matsya Purana also detail the incident.
Daksha was one of the Prajapati, son of Brahma, and among his foremost creations. The name Daksha means "skilled one". Daksha had two wives: Prasoothi and Panchajani (Virini). Sati (also known as ‘‘Uma’’) was his youngest daughter; born from Prasoothi (the daughter of the Prajapati Manu), she was the pet child of Daksha and he always carried her with him. Sati (meaning truth) is also called Dakshayani as she followed Daksha’s path; this is derived from the Sanskrit words daksha and ayana (walk or path).
Sati, the youngest daughter of Daksha, was deeply in love with the god Shiva and wished to become his wife. Her worship and devotion of Shiva strengthened her immense desire to become his wife. However, Daksha did not like his daughter’s yearning for Shiva, mainly because he was a Prajapati and the son of the god Brahma; his daughter Sati was a royal princess. They were wealthy nobility and their imperial royal lifestyle was entirely different from that of Shiva. As an emperor, Daksha wanted to increase his influence and power by making marriage alliances with powerful empires and influential sages and gods.
