The book, "All about Hinduism" by Swami Sivananda discusses aspects of Vishisthadvaita, theological school founded by Ramanuja. Vishisthadvaita is a qualified monism in which God alone exists but admits plurality. By holding such beliefs, Vishisthadvaita is midway between Advaita and Dvaita.

Vedanta (Vedānta, वेदान्त vedānta), a tatpurusha compound of veda "knowledge" and anta "end, conclusion", translating to "the culmination of the Vedas".
All forms of Vedanta are drawn primarily from the Upanishads, a set of philosophical and instructive Vedic scriptures, which deal mainly with forms of meditation.
The epistemology of Advaita, Vishishtadvaita and Mimamsa (ie, purva-) is common.
Vedanta (meaning literally the end of the Vedas) is a branch of Hindu philosophy.
It relies on the Upanishads, which are known as Vedanta due to their containing the end and fundamental essence of all the Vedas, and some of the earlier Aranyakas.
But, consistent throughout Vedanta is the authoratative declaration that ritual is to be eschewed in favor of intuitional questing for truth, for meditation governed by a loving morality, secure in the knowledge that infinite bliss does await her/him who seeks beyond the mere body and mind for it.
