AUM is one of the religious tattoo patterns. The twisted figure is not very large, and it looks very simple. It belongs to a rather sacred symbol in Hinduism, representing the combination of universe and eternity, material and divinity.

The three letters of the AUM symbolize the three Hindu envoys. There are even some yoga practitioners who think that chanting AUM can lead to meditation. But this pattern seems to have no amulet meaning.
