Rajendra, nicknamed 'The Lawyer-Poet', writes controversial poems that address human rights and environmental problems. As an attorney, his work has focused on helping poorer people who are in need of legal aid. He is a co-founder of Penang Legal Aid Centre (PLAC).
Working with photographer Ismail Hasim, Rajendra explored the backstreets of the island of Penang before the pair compiled and published Scent of an Island, a collection of poetry and black-and-white photographs of Penang.
In 1993 he had his passport taken from him by the Malaysian government, to prevent him from traveling. A Malaysian High Commission spokesman stated, "Mr Rajendra's passport was retained for his anti-logging activities, which it was felt could damage the country's image overseas".
In 2005, Rajendra was awarded the first Malaysian Lifetime Humanitarian Award "in recognition of his pioneering legal aid work and exemplary poetry".
