Question

how did raja ram mohan roy use sacred scriptures to work for reform​

Answer 1

      He is a great historical figure, who put laudable efforts to transform the face of India and dared to defy the age-old Hindu traditions. A modernist by virtue, he undertook a lot of social reforms to change the society and worked for the upliftment of the status of women in India. He was also a great scholar who translated many books, religious and philosophical work and scriptures into Bengali and also translated Vedic scriptures into English.

Answer 2

The Bengal society was weighed down with an array of evil customs and regulations. There was a huge prevalance of intricate rituals and scrupulous moral codes which were largely modified and badly elucidated ancient traditions. He was against traditional Hindu practices and echoed his voice against Sati system, polygamy, caste rigidity and child marriage. His biggest achievement was the prohibition of the “sati pratha”, a practice in which a widow was made to immolate herself at the funeral pyre of her deceased husband. He struggled for years to get this evil legally eradicated.
He established the Brahmo Samaj along with the other enlightened Bengalis. The samaj was a highly influential socio-religious reform movement which raised its voice against evils like caste system, dowry, ill-treatment of women, etc.
