Morgan's Philosophy of Homeopathy, at last made him convert to the new system. He was soon to become the best Indian homeopath of the day. Vidyasagar himself acquired a tolerable knowledge of the science and used to treat simple cases. He purchased several volumes of works and studied them. Many poor people received medical aid at his hands. He wanted to popularise these drugs since they were cheap, yet potent.
In later years he used to repair to Burdwan to recuperate his health, it being then one of the best sanatoriums in Bengal. Several times he was an honoured guest of Babu Pyari Chand Mitra; afterwards he lodged in a rented house. His cook, to whom he was warmly attached, generally accompanied him. Once he took a beggar woman to task for coming so often to ask charity. Vidyasagar, being within earshot, accidentally overheard this and forthwith pensioned off the old servitor. He never suffered anybody to turn a beggar out of doors.
