Sunil is a fan of all festivals in India but Rath Yatra* is one of his favorites. Every year he celebrates with a miniature version of the three huge chariots used in the main celebration in Puri (on the Bay of Bengal south of Kolkata).
This festival is also celebrated in Kolkata and for a week you will see pop-up stands selling small replicas of the chariots used to carry Lord Jagannath and his entourage. Pulling the chariot is considered an auspicious deed - for all the years that Sunil has pulled his chariot we expect he has accumulated a lot of good karma.
*Wikipedia: Ratha Yatra or Ratha Jatra or Chariot Festival is a Hindu festival associated with Lord Jagannath held at Puri in the state of Odisha, India.
