Quotes:Adwaita
Blavatsky, Helena Petrovna
Adwaita. A Vedânta sect. The non‐dualistic (A‐ dwaita) school of Vedântic philosophy founded by Sankarâchârya, the greatest of the historical Brahmin sages. The two other schools are the Dwaita (dualistic) and the Visishtadwaita; all the three call themselves Vedântic.
