Devotion to Vishnu is at the core of Sri Vaishnavism, a Hindu sect that follows the teachings of Ramanuja. This devotion is seen as the primary means of attaining salvation and liberation from the cycle of birth and death.

In Sri Vaishnavism, Vishnu is revered as the supreme deity and the ultimate source of all existence. He is believed to be the creator, sustainer, and destroyer of the universe. Devotees of Sri Vaishnavism see Vishnu as the ultimate object of love and devotion, and they strive to cultivate a deep and personal relationship with him.

One of the key aspects of devotion to Vishnu in Sri Vaishnavism is the concept of Prapatti, which means surrender. This surrender is not just a physical act, but also a mental and emotional surrender to Vishnu. It involves complete faith and trust in Vishnu's grace and a willingness to let go of one's ego and desires.

Devotees of Sri Vaishnavism also engage in various devotional practices, such as prayer, chanting of Vishnu's names, and offering of flowers and food to Vishnu's idols. These practices are seen as a way to express one's love and devotion to Vishnu and to seek his blessings.

Another important aspect of devotion to Vishnu in Sri Vaishnavism is the belief in the power of Vishnu's grace. It is believed that through devotion, one can attain Vishnu's grace, which can lead to liberation from the cycle of birth and death. This grace is seen as a gift from Vishnu and cannot be earned through any other means.

Moreover, devotion to Vishnu in Sri Vaishnavism is not limited to just rituals and practices. It also involves leading a virtuous and ethical life, following the principles of dharma, and serving others. This is because true devotion to Vishnu is not just about seeking personal salvation, but also about selfless service and compassion towards others.

In conclusion, devotion to Vishnu is of utmost significance in Sri Vaishnavism as it is seen as the path to attaining salvation and liberation. It involves surrender, faith, and love towards Vishnu, and is expressed through various devotional practices and a virtuous way of life. Through devotion, one can experience the divine grace of Vishnu and ultimately merge with him.
