Lord Brahma had two sons. ‘Narad’ and ‘Daksha’.
Lord Brahma requested Narad to create Universe but as Narad was divine sage and not interested the request was forwarded to Daksha . Universe was created. Daksha was unanimously selected as the leader and was named as Daksha Prajapati.
Once at Allahabad Yagya was organized by Daksha Prajapati. Each and every person presented at the Yagya site paid standing respect to Daksha except Lord Shiva which was not liked by Daksha Prajapati. He with bad intention once again organized Yagya at Kankhal, Haridwar and invited all Devtaas except Lord Shiva and Goddess Uma – his daughter. But Uma attended the Yagya without any invitation and was insulted by her father. She jumped into the Yagya Kund and killed herself.
Daksheshwar Mahadev temple is the location where Yagya was organized by Daksha Prajapati and Uma (Sati) killed herself and finally Daksha Prajapati was killed by Lord Virbhadra.
