Ramanuja was a prominent Indian philosopher and theologian who lived in the 11th century. He is best known for his teachings on Vishishtadvaita, a form of Vedanta that emphasizes the importance of devotion to God while recognizing the individual soul's unique relationship with the divine. His ideas helped shape the Bhakti movement, which encouraged personal devotion and love for God. Ramanuja's influence extended beyond philosophy; he also played a significant role in promoting social equality and inclusivity within Hinduism. His writings, such as the Sri Bhashya, continue to inspire millions, making him a key figure in the spiritual landscape of India.
