Dr Siddhartha Ganguli is one of the very few hardcore scientists in the world today who have been looking at different domains from multi-disciplinary angles. The fruits of his painstaking research and unstinted expressive labour are available to us today by way of Bio-musicOlogy, BaulOlogy, LoveOlogy, and now SoulOlogy through the present trend-setting volume. Such effective inter-mingling of arts and sciences has been possible because of his extensive travels in the realms of engineering, biomedicine, behavioural science, economics and business management, performing arts and brain sciences & neuro-psychiatry. In his such travels, he has firmly held the hands of supergurus like Amartya Sen, John P. Paul, R.M. Kenedi, D.C. Simpson, Roger Sperry, Pt. Ravi Shankar, Satyajit Ray, Mother Teresa and Peter Drucker. Author of thirty books and over seven hundred and fifty published articles, Dr Ganguli has travelled and lectured worldwide. His awards and honours include the President of India Prize, the Nehru Medal and the Golden Peacock from India and special recognition from the British Council, UK, the Governments of Canada & Australia and Philips International, Eindhoven.
