During my last two weeks in Tokyo, I taught evening classes exclusively at YogaPlus, Shinjuku. I would take the train from Gotanda to the busiest subway station in the world, maneuver my way through the maze of stairs, tunnels and people and then walk out  towards the bright glowing web of flashing lights.  I explored the narrow the streets of Shinjuku enveloped in a persistent kinetic hum but  was surprisingly able to tap into my own inner silence and walk in solitude.
