In the meantime there friction between him and Ethel Mary. The cause could have been Coomaraswamy's studies. She was young and wanted to go places and enjoy life. But her husband was always immersed in his studies. Their ways were different and a disappointed Ethel Mary went back to her country.

Several months went by and Coomara swamy's studies went on uninterrupted. He also developed on interest in the study of Indian music.During this time he came to know a Ceylonese girl called Ratna Devi. Later he married her.

Coomaraswamy thought of his studies day and night. He was not content to learn only through books. He wanted to visit India and see for him what he had learnt from books.

But he was the Director of Mineralogical Survey, an employee of the Ceylon Government. He held a high and responsible position and much of his time was taken up by his official duties. He resigned his post so that he could pursue his studies.

Even though he was totally involved in his studies Coomaraswamy did not forget the world around him. He worked hard to eradicate the evils in society. He established 'Ceylon Social Reform Society. He started a newspaper called 'Ceylon National Review'.
