This is the Hindu self-sacrifice ritual under the Divine Wheel of the Jugganaut. They have been doing this centuries.
They believe im reincarnation and believe that by dying in the most holy state (under the Wheel of Saturn) they will respawn at a better level.
Our cultural equivilent would be setting off on a quest for the Grail and being crushed by King Arthur's Round Table and respawning as one of his knights.
Most cultures have the same wheel motif somewhere but only Indians put it on their flag and act it out to this day.
