A Conversation (Between Yama and Yudhishthira)
One day, in the forest, the god of Death Yama asked the mighty hero Yudhishthira: “What is the most wonderful thing in this world?”. Yudhishthira answered: “The most wonderful thing in this world is that, despite the countless number of people passing away every day, the rest still hopes to live forever.”
Mahabharata, Book 3, 311-312
According to Hinduism, cremation is sacrifice, and sacrifice regenerates the cosmos. Thus, since funeral pyres are uninterrupted in Varanasi, the process of creation is continually repeated.
