Various social reformers and organizations are as follows: Arya Samaj It was founded by Swami Dayanand Saraswati in 1875. The main aim of Arya Samaj is to make a casteless society, abolish Sati and encouraging widow-remarriages, and provide education for all. Dayanand Saraswathi propagated the infallibility of the Vedas. He also encouraged inter-caste marriages. Ram Krishna Mission: Ramakrishna's Mission was started by Swami Vivekananda and his handful of associates. The mission bases its work on the principles of karma yoga, the principle of selfless work done with a dedication to God. The Ramakrishna Mission has centered around the world and publishes many important Hindu texts. Brahmo Samaj: Raja Ram Mohan Roy founded Brahmo Sabha in 1828, which was later renamed Brahmo Samaj. Its chief aim was the worship of the eternal God. It was against priesthood, rituals, and sacrifices. It focused on prayers, meditation, and reading of the scriptures. It believed in the unity of all religions. Scientific Society: The Scientific Society of Aligarh or The Scientific Society was founded by Sir Syed Ahmed Khan in 1864. In 1862 Syed formed a Translation Society which used to translate the scientific books of English and other European languages into Urdu and Hindi. This society later evolved into the Scientific Society of Aligarh. The society sought to promote liberal, modern education and Western scientific knowledge in the Muslim community in India. Thus, we can conclude that Swami Ramakrishna was not the founder of Brahmo Samaj.
