See this video of how a Yazidi priest is giving Tilaka to a visiting devotee in the same way like Hindu priests make Tilaka to visiting devotees all over India, one Tilaka mark on the forehead, on the Ajna Chakra, and the second on the throat. on the Vishuddhi Cakra. Amazing. They also have a caste system, walk around sacred objects 3 times which is called “Parikrama” in Hinduism and consider trees holy.
