Author Aatish Taseer was born in the UK, the son of prominent Indian journalist Tavleen Singh and Pakistani politician, Salmaan Taseer. For his new book, "The Twice Born: Life and Death on the Ganges," Taseer traveled to Benares, the spiritual home of Hinduism for an up-close look at what the caste system means in India today.
Taseer says caste, the social and religious hierarchy of Hinduism, can have profound impacts on the trajectory of a person's life and governs any number of social interactions. It remains resilient in modern India, and Taseer considers its link to the rise of the Hindu nationalism.
