Dakshayagna.

Dakshayagna is a pivotal tale in Hindu mythology. It recounts the grand sacrifice ritual organized by Daksha, where his daughter Sati, wife of Lord Shiva, tragically immolates herself due to her father's insult to her husband. Enraged by this, Shiva destroys the sacrifice, leading to the creation of the Shakti Pithas. This event also sets the stage for the reincarnation of Sati as Parvati, who later marries Shiva. The story is central to understanding the complexities of Hindu deities and their interactions.
