The gods need Shiva to marry Parvati, so Indra sends Kama, the god of love, with his wife Rati and his friend Spring. Kama shoots Shiva with an arrow of flowers, and Shiva opens his third eye and burns him to ash. Rati's grief moves Shiva to promise that Kama will live again. Tamil Nadu keeps the Holi full moon as Kaman Pandigai.

Pan-IndiaShaiva🪔 Holi
With the gods unable to defeat Taraka, Indra calls Kama and asks him to wake Shiva's love for Parvati. Kama goes with Rati and Vasanta; the forest blooms out of season. As Parvati comes to worship, Kama shoots Shiva with his flower arrow. Shiva's mind is stirred; he looks round, sees Kama with his bow drawn, and from his third eye a fire leaps out that burns Kama to ash. Rati laments over the ashes. The gods plead; Shiva promises that Kama will be born again as Pradyumna, son of Krishna and Rukmini.
Some days before the Phalguna full moon a castor stalk is planted as Kama's flag in the village. Each night people sing Rati's lament. Two sides argue in song, one saying Kama was burnt, the other that he was not. On the full moon a figure of Kama is burnt; sandal paste is put on the ashes to cool his burns, and he is said to come back to life.
What is different here:
A village festival with a flag, songs and a debate; Kama comes back on the night itself.
