In Vishishtadvaita, the relationship between the individual soul and the universal soul is one of inseparable unity with distinct differences. This philosophy, founded by Ramanuja in the 11th century, believes that the individual soul (jiva) and the universal soul (Brahman) are not separate entities, but rather intertwined and dependent on each other.

According to Vishishtadvaita, the individual soul is a part of the universal soul, much like a drop of water is a part of the ocean. This means that the individual soul is not a separate entity, but rather a manifestation of the universal soul. This concept is known as "Soul-dependence" or "Soul-bondage", where the individual soul is bound to the universal soul and cannot exist without it.

However, this does not mean that the individual soul loses its identity or becomes absorbed into the universal soul. In Vishishtadvaita, the individual soul retains its unique characteristics, experiences, and actions, while still being connected to the universal soul. This is known as "Soul-individuality", where the individual soul maintains its individuality while being a part of the universal soul.

The relationship between the individual soul and the universal soul is also described as that of a body and its limbs. Just as the limbs are an integral part of the body, the individual soul is an integral part of the universal soul. The limbs cannot function without the body, and similarly, the individual soul cannot exist without the universal soul.

Moreover, the individual soul is considered to be a reflection of the universal soul. Just as a mirror reflects the image of an object, the individual soul reflects the qualities and attributes of the universal soul. This reflection is not a mere imitation, but a true manifestation of the universal soul's essence.

In Vishishtadvaita, the ultimate goal is for the individual soul to realize its unity with the universal soul. This is achieved through devotion and surrender to the universal soul, known as "Bhakti". By surrendering to the universal soul, the individual soul can overcome its limitations and attain moksha (liberation) from the cycle of birth and death.

In conclusion, the relationship between the individual soul and the universal soul in Vishishtadvaita is one of inseparable unity with distinct differences. The individual soul is a part of the universal soul, retains its individuality, and is connected to the universal soul through devotion and surrender. This philosophy emphasizes the importance of recognizing the unity of all beings and the ultimate goal of realizing our oneness with the universal soul.
