In brief
Vishishtadvaita is Ramanuja’s qualified non-dualism: Brahman is the one reality, and individual selves and the world are real, existing as Brahman’s body rather than as a second reality. Because the self stays a real part of the divine, devotion, bhakti, becomes the highest path rather than a preliminary.
Vishishtadvaita is usually translated as qualified non-dualism, and the qualification is the whole argument. Ramanuja, writing in the eleventh century, accepted that there is one reality without a second. What he rejected was the conclusion that this one reality must therefore be without internal distinction. His position is that Brahman is one, and that individual selves and the material world are real, and that these are not competing statements because the selves and the world exist as the body of Brahman rather than alongside it.
The body analogy is doing precise work. Your body is not separate from you, and it is also not identical to you in the way that would make the word body meaningless. It is dependent, inseparable, and genuinely there, with characteristics of its own. Applied to the cosmos, this lets Ramanuja say that a person is really a person, that the world really has the properties it appears to have, and that neither of these facts introduces a second reality, because both are modes of the one.
The consequence that mattered most to him was devotional. If the individual self is finally identical to the absolute without remainder, then love between them is a temporary arrangement that dissolves on realisation. If the self is a real and permanently distinct part of the absolute, then the relationship survives, and bhakti becomes not a preliminary practice for those not ready for knowledge but the highest thing available. This is also why divine energy and divine attributes are treated as fully real in his system rather than as concessions to a lower level of understanding.
Vishishtadvaita is the argument that oneness does not have to be featureless to be one. To see how a third school pushed the distinction further still, explore more of The Living Sanatan Timeline.
Questions people ask
Vishishtadvaita, qualified non-dualism, is the Vedanta school systematised by Ramanuja in the eleventh century. It holds that reality is one, Brahman, but internally differentiated: souls and matter are real and inseparable from Brahman as its body.
Advaita holds that Brahman is without any distinctions and that the individual self is finally identical to it. Vishishtadvaita holds that selves and world are real modes of Brahman, so the distinction between devotee and God is never erased.
Just as your body is real, dependent on you and inseparable from you without being identical to you, the world and souls are the body of Brahman. This lets them be fully real without becoming a second reality.
If the self remains a distinct part of Brahman, the relationship of love between soul and God survives liberation. Bhakti is then the highest end, not a stage for those unready for knowledge. The school underlies the Srivaishnava tradition.
