He later went to India to study Vanga (Bengali) and Hindi and Bharata culture. When he came to Sri Lanka he joined the editorial board of the then 'Heladiva' newspaper. After being released from clergy, he composed the play Dugi Hanga in 1947. He also wrote articles for the 'Heladiva' newspaper. Then he wrote a column called 'Charumanda' in "Hela Diva".
