When you hear the name “Babur”, both sides – Hindus and Muslims – get excited. In Bombay you will get a Hindu backlash, in Hyderabad a Muslim backlas… - Jeet Thayil

I’ve spent a lot of time in London over the last few years and I liked the idea of the Mughal emperor Babur meeting with modern-day disaffected youth and talking to them about their actions. He was a sharp literary critic who could be very sweeping and cruel about poetry if he thought it was bad poetry, and he said some fantastic things that I quoted word for word in the opera. I read the Baburnama – the memoirs of Babur – and quoted lines from it. “Writing badly will make you ill.” What a beautiful thing to say. I read that book and I thought, how dramatic! If he had been a figure in western history it would have been an opera. War, murder, love, tragedy, poetry. It always jumped out at me as something worth doing.

Opium use is a quick way of showing a person’s character. Within months some people would be stealing from family and friends, but there were people who never did that kind of thing. I used my salary to finance my habit.

The thing about opium is that it makes you vomit. You cook the original raw sticky pellet against the bowl of the pipe. And for the first three or four months, you puke. But it’s a clean very easy puke, not like alcohol. You could be walking down the street talking to a friend, turn, puke and keep going. But you do that a lot for the first few months. It takes devotion to become an addict to opium and heroin. You have to keep doing it to get through it. I lost a lot of weight. But the payback is huge. It is pure pleasure. There is a reason why opiates are used as a painkiller: they make you feel better. They’re designed to make you feel better.
