Ven Soma thero followed the example set by his teacher, Most Ven Madihe Pannaseeha thero and served the Buddha Dhamma and the Sinhala Buddhists both as a learned monk and as a social reformer.
Venerable Gangodawila Soma Thera of the Vajiraramaya Maharagama died in St. Petersburg, Russia on 12 December 2003 in his 56th year. He was in Russia to accept an honorary doctorate conferred by the Russian Government. He was rushed to a hospital in St Petersburg after a heart attack. He underwent two emergency operations.
Sri Lankans were shocked and saddened by his death. The circumstances of his death aroused suspicion. It was widely believed that he was murdered by Christian fundamentalists. Therefore two autopsy tests were carried out. A commission was appointed to investigate the death. Out of the four people in the commission, 3 deduced that it was intentional but the other thought the evidence was not enough.
