Vedanta is the inquiry into and systematisation of the Vedas and Upanishads, to harmonise the various and contrasting ideas that can be found in those texts. Within Vedanta, different schools exist:<ref>Wilhelm Halbfass (1995), Philology and Confrontation: Paul Hacker on Traditional and Modern Vedanta, State University of New York Press, {{ISBN|978-0791425824}}, pages 137–143</ref> 
* [[Advaita]], unqualified [[nonduality]], is the school of [[Adi Shankara]];
* [[Vishishtadvaita]], qualified monism, is from the school of [[Ramanuja]];<ref>Jeaneane Fowler (2012), The Bhagavad Gita: A Text and Commentary for Students, Sussex Academic Press, {{ISBN|978-1845193461}}, page xxviii</ref>
* [[Shuddhadvaita]], in-essence monism, is the school of [[Vallabha]]; 
* [[Dvaitadvaita]], differential monism, is a school founded by [[Nimbarka]]; 
* [[Achintya Bheda Abheda]], a school of [[Vedanta]] founded by [[Chaitanya Mahaprabhu]] representing the philosophy of ''inconceivable one-ness and difference''. It can be understood as an integration of the strict dualist (dvaita) theology of [[Madhvacharya]] and the qualified monism (vishishtadvaita) of [[Ramanuja]].
