Siddhanta

'''' (Devanagari: ) is a Sanskrit term denoting the established and accepted view of any particular school within Indian philosophy; literally "settled opinion or doctrine, dogma, axiom, received or admitted truth; any fixed or established or canonical text-book on any subject" (from siddha, adj. mfn.- accomplished, fulfilled; that has attained the highest object, thoroughly skilled or versed in).

==Hindu philosophy== This term is an established term within Hindu philosophy which denotes a specific line of development within a Hindu religious or philosophical tradition. The traditional schools of Hindu philosophy have had their siddhāntas established by their respective founders in the form of sūtras (aphorisms). The sūtras are commented by a major philosopher in the respective traditions to elaborate upon the established doctrine by quoting from the śāstras (scriptures) and using logic and pramāṇas (accepted source of knowledge). For example, in the tradition of Vedanta, the author of the Brahma Sūtra was Veda-Vyāsa and the commentators were Ādi Śaṅkara, Rāmānuja and Mādhavācārya (each of whom eventually set up sub-schools within Vedānta). Also, in the tradition of Pūrva Mīmāṁsā, the author of the sūtra was Jaimini and the commentator was Śabarasvāmi.
