"Hash house harrier"

I was wandering through the twisted labrynth of old Varanasi when this gentleman, a holy Nagababa - whose brethren famously smear themselves in ashes from crematorial fires and partake of human flesh - came sweeping past. Intrigued by his purposefulness (his gaze was fixed straight ahead, and he was walking unimaginably fast), and by the effect he was having on the crowd as he progressed (like Moses parting the Red Sea, so powerful was he...), I decided to follow at a distance. Twenty long minutes and maybe two miles later, he turned into a tiny lane in which the only sign of life was a man with a tray of green balls for sale. The Naga's intense Grail Quest was merely an urgent visit to his marijuana dealer.
