Sri Vaishnavism is a Hindu sect that centers around the devotion to Vishnu, one of the three main deities in Hinduism. It follows the teachings of Ramanuja, a prominent theologian and philosopher who lived in the 11th century. Sri Vaishnavism is known for its emphasis on devotion and surrender to Vishnu, as well as its belief in the concept of grace and the importance of community.

One of the main differences between Sri Vaishnavism and other Hindu sects is its belief in the concept of grace. In Sri Vaishnavism, it is believed that salvation can only be attained through the grace of Vishnu, and not solely through one's own actions or efforts. This idea of grace is known as "prapatti" and is seen as the ultimate act of surrender and devotion to Vishnu. This sets Sri Vaishnavism apart from other Hindu sects that may place more emphasis on individual efforts and actions for attaining salvation.

Another distinguishing factor of Sri Vaishnavism is its emphasis on community and the importance of the guru-disciple relationship. In this sect, the guru is seen as a vital guide for spiritual growth and is believed to have a direct connection with Vishnu. The guru is seen as a representative of Vishnu and is given great respect and devotion by followers. This emphasis on the guru-disciple relationship is not as prominent in other Hindu sects.

Sri Vaishnavism also has a unique interpretation of the Vedas, the sacred texts of Hinduism. While other sects may interpret the Vedas in a more literal or philosophical manner, Sri Vaishnavism sees the Vedas as a means of understanding the nature of Vishnu and his relationship with humanity. The teachings of Ramanuja, which are based on his interpretation of the Vedas, also play a significant role in shaping the beliefs and practices of Sri Vaishnavism.

In terms of practices, Sri Vaishnavism differs from other Hindu sects in its emphasis on bhakti, or devotion, as the primary means of attaining salvation. This devotion is expressed through various rituals, prayers, and devotional songs, all centered around Vishnu. Sri Vaishnavism also places great importance on the worship of Vishnu in his various forms, such as Rama and Krishna, and the recitation of his names, known as "nama sankirtan."

In conclusion, Sri Vaishnavism stands out from other Hindu sects for its emphasis on devotion, grace, community, and the guru-disciple relationship. Its unique interpretation of the Vedas and practices centered around bhakti make it a distinct and influential sect within Hinduism.
