Saint, Peace Seeker, Hero by Turns

He lies flat on the ground, turning himself over and over like a runaway log, limbs flailing as he bumps across potholes, splashes through mud puddles and falls deeper into a spiritual trance.

Stretched out in the middle of the road, rolling hour after hour, mile after mile through crowds and heavy traffic, he is making his trip to eternal bliss. But this is no ordinary holy roller. He is also on a mission to bring peace to the world. He has rolled thousands of miles in the last 19 years, turning round and round so many millions of times that just pondering the thought can make your head spin. Yet to the 55-year-old sadhu, the constant turning is refreshing. As a sadhu, the Rolling Baba is a wanderer who survives on alms. Apology by Plato. Philosophy bites.
