Kunal Mishra 11 months, 1 week ago

Kathmandu summary will help students learn about the story written by Vikram Seth, which is an excerpt from his book ‘Heaven Lake’. This story tells us about the author’s visit to the capital of Nepal, Kathmandu. We see that he was coming from China to visit India via hitchhiking. In this hitchhiking, he crosses Tibet and Nepal. Thus, this story gives us an account of his experience in Kathmandu. This travelogue gives an insight on his trip to the city and what he feels about it. On his trip to Kathmandu, Vikram visits the two most popular temples of the city. One is the Pashupatinath temple and the other is Baudhnath Stupa. He notices the difference between the two temples and the atmosphere surrounding them. Thus, through Kathmandu summary, we travel to the city without actually going there, through Vikram’s magical words.
