He is among thousands of Burmese Tamils living in the north-eastern Indian town of Moreh in Manipur state, which borders Myanmar, also known as Burma. Mr Sarlan and other Indian-origin people were forced to leave the country following a military coup in the 1960s. Their businesses were nationalised and Mr Sarlan, who used to live in Rangoon (now called Yangon), and others became penniless refugees overnight.
Mr Sarlan has spent most of his life as a refugee. It is estimated that nearly 300,000 Indians fled the country following the coup. "After we reached India, for the first three months we were living in a refugee camp in the southern state of Tamil Nadu. Though Tamil Nadu was the land of our forefathers, it was difficult to live there without any support," recalls Mr Sarlan, 74, who is now a social activist.
Burmese nationalists always viewed them with suspicion and there were a series of anti-Indian riots in the 1930s. Once the British left in 1948, Indian-origin people became increasingly vulnerable and they were swiftly forced to leave following the 1962 coup.
They found it difficult to settle in India, so many decided to return to Burma by land. They vaguely knew that India's north-eastern states of Nagaland, Manipur, Mizoram and Arunachal Pradesh shared a border with Burma.
After weeks of travelling by train and bus a small group managed to reach Moreh, around 3,200km (2,000 miles) by road from Tamil Nadu. When they reached the border crossing, Burmese soldiers prevented them from entering the country. The Tamils settled in Moreh hoping one day to return to their homeland - but those dreams have never been fulfilled.
"Moreh was a tribal village when we first came here. There was hardly any infrastructure at that point. But many Burmese people came to Moreh looking for Indian goods like automobile parts, clothing and cosmetics. Since we knew the Burmese language it was easy for us to start businesses," Mr Sarlan recalls.
Soon, the Tamils in Moreh invited their relatives and friends from camps in Tamil Nadu and elsewhere to join them. Many went on to become Indian citizens. By the 1990s the number of Burmese Tamils in Moreh had increased to about 15,000, almost half of the town's population. They had set up their own schools, temples, churches and mosques - and celebrated their cultural festivals with fervour. Moreh was described as a "mini-India".
"We still retain lots of cultural and social links with Tamil Nadu state. For our important temple festivals we bring priests and music performers from there. Many parents in Moreh also send their children to schools in Tamil Nadu," says K Balasubramaniam, who is the principal of a local secondary school.
"We take part in each other's cultural and religious festivals. We have several committees to look into any problems and they get sorted out immediately," says Manohar Mohan, a Tamil businessman.
Tamil businesses suffered a setback after the Burmese government established a market just inside their border in Namphalong in the mid-1990s. Chinese products flooded in and many Burmese started shopping in Namphalong rather than Moreh.
Traders in Manipur also faced threats from insurgents in the state - some of the businessmen who refused to pay "extortion money" were shot dead. The violence and lack of business opportunities forced many traders and Burmese Indians to leave Moreh, many opting for Chennai. Now Moreh's Tamil population is just 3,500.
Moreh is considered to be India's gateway to South East Asia and locals believe because of its unique geography the place offers tremendous potential. The story of the town's Burmese Tamils is one of suffering and resilience as well as achievement.
Many elderly Tamils, originally from Burma, are nostalgic and want to stay in Moreh, as it is closer to where they come from. But later generations say the town offers little in terms of education and employment.
