The main subject of Upanishads is the discussion about Paramatmatattva. There are two kinds of Vidyas : Para (पराविद्या) and Apara (अपराविद्या). Of these Paravidya is supreme and is called Brahmavidya (ब्रह्मविद्या). Upanishads present the detailed discussion about Paravidya. Aparavidya is primarily related to Karmas, hence called Karmavidya (कर्मविद्या). The fruits of Karmavidya are perishable while the results of Brahmavidya are indestructable. Aparavidya may not lead one to Moksha (may lead to svarga and other worlds) but Paravidya always gives Moksha.<ref name=":42222" /> The central concepts found in the Upanishads involve the following aspects of Sanatana Dharma<ref name=":1" /><ref name=":22" /><ref name=":022">''Sanatana Dharma : An Advanced Textbook of Hindu Religion and Ethics''.
