Early in the morning the lake was pristine, and the village above it was serene. A boatman with a weathered countenance offered us admittance to his little ferry for ten rupees. His voice was mellifluous, his directions lucid, and his stories eloquent enough to make the crossing feel short. The mist was ephemeral; by nine it had gone. Phones are ubiquitous even here, yet the people seemed resilient in an older way, and the breakfast of beaten rice and tea was wholesome.
