Acharya Ramanuja, also known as Ramanujacharya or Ramanujacharyulu, was a prominent theologian, philosopher, and proponent of the Sri Vaishnavism tradition within Hinduism. He lived from 1017 to 1137 CE and is considered one of the most influential figures in Indian philosophy and the Bhakti Movement. Here are key aspects of Acharya Ramanuja’s life and teachings:

1. Early Life and Education: Ramanuja was born in Sriperumbudur, Tamil Nadu, into a Brahmin family. He showed an inclination towards spirituality and learning from a young age. He studied the Vedas, Upanishads, and other Hindu scriptures under the guidance of his guru Yadava Prakasha.
2. Philosophical Contributions: Ramanuja’s philosophical contributions primarily revolved around the Vishishtadvaita Vedanta (qualified non-dualism) school of thought. He synthesized the teachings of earlier philosophers like Shankaracharya and emphasized the concept of qualified non-dualism, asserting that the individual souls (atma) are distinct from the supreme reality (Brahman) but are also interconnected with it.
3. Devotion to Lord Vishnu: Ramanuja was a devout follower of Lord Vishnu and advocated the path of loving devotion (bhakti) as a means of attaining spiritual liberation (moksha). He stressed the importance of surrendering to the divine grace (prapatti) and cultivating a deep personal relationship with Vishnu through devotion, prayer, and ethical living.
4. Equality and Social Inclusivity: One of Ramanuja’s significant contributions was his emphasis on social inclusivity and equality within the Sri Vaishnavism tradition. He actively opposed caste-based discrimination and opened up the path of devotion to people from all backgrounds, including lower castes and women, challenging prevailing social norms of his time.
5. Works and Commentaries: Ramanuja authored several important works, including commentaries on the Brahma Sutras (Sri Bhashya), Bhagavad Gita (Gita Bhashya), and the Vishnu Purana. His commentaries provided deep insights into Vedanta philosophy, Bhakti yoga, and the nature of reality according to Sri Vaishnavism.
6. Legacy and Influence: Ramanuja’s teachings had a profound impact on Hindu philosophy, theology, and religious practices. His followers established the Sri Vaishnava tradition, which continues to thrive, particularly in South India. His emphasis on devotion, inclusivity, and philosophical insights influenced subsequent Bhakti saints, thinkers, and religious leaders.

Overall, Acharya Ramanuja’s life and teachings exemplify the Bhakti Movement’s spirit of devotion, inclusivity, and philosophical exploration within the Hindu tradition, leaving a lasting legacy in Indian spirituality and philosophy.
