"Sarhul" is a major Tribal festival from Jharkhand celebrated mainly by the Jharkhandi Tribes such as Oraon(Kurukh), Santhalis, Ho, Kharias, Bhumij and Mundas. Sarhul symbolizes the marriage between the Earth(Dharti Ayo) and the Sun (Biri). In this festival, people worship in "Sarna" which is a sacred grove of the Sal/Sakhua/Sarai tree where they gather to worship the Centuries-Old "Living Tree Goddess". On the occasion of the festival, people go to "Sarna" to the beats of Dhol, Nagara and Mandar while singing the centuries old folks songs throughout their way. (Note:-My cousin is singing this btw)
