He began chain-smoking as a third-grade student. In 1961, when he was a prominent member of the Communist Party in Siliguri, he had to appear before a general body meeting of the local party unit to face charges of public drunkenness. A year later, he fought an Assembly by-election on a CPI ticket only to lose badly, polling just about 3,500 votes. And in 1964, coming out of a group meeting at a party comrade’s house in Darjeeling, he collapsed, complaining of severe chest pain.
