Flickr user fredcan took this intriguing photo of a naga sadhu [wiki]:
Shivraj Giri is a very charismatic naga sadhu i spent some time with in Varanasi in February 2007. Here, taking a little chai (tea) break. Indian pilgrims would sometimes wait in line in front of him to receive his darshan (blessing), making him a very popular and busy man in Varanasi.
When not on the pilgrimage routes, Shivaraj Giri lives away from the chaos of the world, just outside a tiny village in Madhya-Pradesh (central India), where his desciples and villagers regularly go and pay him respectful visits.
What is a sadhu? It's an ascetic or yoga practitioner who renounced all material things in order to achieve moksha or liberation through meditation.
