This is for the city dwellers, those who do not, cannot walk around bare foot, or otherwise.
Those who have to travel amidst pollution almost everyday and feel miserable about it.
Those who love moving their bodies for no reason. (For ex, my wiggling toes, thinking that they are typing.)
Please try this and let me know if you get it. I remember a very clear image. A bus. Me and a cousin, just into teenage. We were sitting on the last row of seats. The cousin smiling impishly, and moving his body along with the jerky movements of the bus. It somehow looked rhythmic, almost like a dance. He was also tonelessly humming along, which means his breath was also co-ordinated with the movements of the bus.
This, by the way, is the first step. Swamiji will take you higher, I assure you.
