According to Ramanuja, the concept of moksha in Vishishtadvaita Vedanta is the ultimate goal of human life, which is achieved through the realization of the oneness of the individual soul (jiva) with the supreme soul (Brahman). Moksha is seen as a state of liberation from the cycle of birth and death, and the attainment of eternal bliss and knowledge.

In Vishishtadvaita Vedanta, moksha is not seen as a separate state or realm, but rather as the realization of the true nature of the self and its relationship with Brahman. Ramanuja emphasizes that the individual soul is not separate from Brahman, but rather a part of it. This concept is known as "tattva-samavaya" or inseparable relationship between the individual soul and Brahman.

The path to moksha in Vishishtadvaita Vedanta involves the practice of three important elements: Bhakti (devotion), Jnana (knowledge), and Karma (action). These three elements work together to help the individual realize their true nature and relationship with Brahman.

Bhakti, or devotion, is seen as the most important aspect in the path to moksha. It involves developing a deep love and devotion towards Brahman, and surrendering oneself completely to the divine. Through bhakti, the individual can develop a personal relationship with Brahman and experience the ultimate bliss and love.

Jnana, or knowledge, is also a crucial element in the path to moksha. It involves understanding the true nature of the self and the universe, and realizing the oneness of all beings with Brahman. This knowledge is gained through studying the scriptures and the teachings of the guru.

Karma, or action, is the third element in the path to moksha. It involves performing selfless actions without any attachment to the results. Through karma, one can purify the mind and cultivate qualities such as compassion, love, and detachment, which are essential for the realization of moksha.

Ramanuja also emphasizes the importance of grace in the attainment of moksha. He believes that the ultimate liberation can only be achieved through the grace of Brahman, which is attained through the practice of bhakti, jnana, and karma.

In conclusion, the concept of moksha in Vishishtadvaita Vedanta is the realization of the oneness of the individual soul with Brahman, achieved through the practice of bhakti, jnana, and karma, and with the grace of Brahman. It is not seen as a destination, but rather a state of being, where the individual experiences eternal bliss and knowledge.
