===Muktika canon: major and minor Upanishads===
There are more than 200 known ''Upanishads'', one of which, the ''{{IAST|[[Muktikā]]}}'' Upanishad, predates 1656 CE{{sfn|Tripathy|2010|p=84}} and contains a list of 108 canonical Upanishads,{{sfn|Sen|1937|p=19}} including itself as the last. These are further divided into Upanishads associated with [[Shaktism]] (goddess Shakti), [[Sannyasa]] (renunciation, monastic life), [[Shaivism]] (god Shiva), [[Vaishnavism]] (god Vishnu), [[Yoga]], and ''Sāmānya'' (general, sometimes referred to as Samanya-Vedanta).<ref>{{Cite book | title = The Samanya-Vedanta Upanishads | publisher = Jain Publishing (Reprint 2007) | isbn = 978-0895819833 |first = T.

Some of the Upanishads are categorized as "sectarian" since they present their ideas through a particular god or goddess of a specific Hindu tradition such as Vishnu, Shiva, Shakti, or a combination of these such as the [[Skanda Upanishad]]. These traditions sought to link their texts as Vedic, by asserting their texts to be an Upanishad, thereby a ''[[Śruti]]''.{{sfn|Holdrege|1995|pp=426}} Most of these sectarian Upanishads, for example the [[Rudrahridaya Upanishad]] and the [[Mahanarayana Upanishad]], assert that all the Hindu gods and goddesses are the same, all an aspect and manifestation of [[Brahman]], the Vedic concept for metaphysical ultimate reality before and after the creation of the Universe.<ref>{{cite book |last=Srinivasan |first=Doris |title=Many Heads, Arms, and Eyes |publisher=BRILL Academic |url=https://books.google.com/books?id=vZheP9dIX9wC&pg=PA111 |isbn=978-9004107588 |year=1997 |pages=112–120 |access-date=8 March 2016 |archive-date=14 May 2016 |archive-url=https://web.archive.org/web/20160514224113/https://books.google.com/books?id=vZheP9dIX9wC&pg=PA111 |url-status=live }}</ref><ref>{{cite book| last=Ayyangar| first = TRS| year=1953| title=Saiva Upanishads| publisher = Jain Publishing Co.
