In Advaita Vedanta it is said that the Ultimate Truth is that Maya never existed, and that there never was a world (Jagat), individual person (Jiva), or a God (Isvara). This is known as Ajata Vada – see here for an example of this teaching. Here in Guru Vachaka Kovai we have Sri Muruganar stating the same:

‘…I have known that in truth there is never in the least any attainment of bondage, liberation, and so on, which are fabricated when one imagines one is separate from reality’ Guru Vachaka Kovai, verse 1241

Someone recently made a comment to me that this sounds remarkably like Neo-Advaita, to which my response was as follows:

They sound remarkably similar because on the verbal level both traditional and neo-Advaita talk about Ajata Vada (the view that there is no maya, no objects truly exist, and therefore no true meaning, no seeker, no teaching, no teacher, etc) as being the ultimate truth, but traditional advaita also talks about teachings from vivarta vada (world is a projected illusion) and shristi dristi vada (world is real) viewpoints and prescribes self-enquiry as a (paradoxically) valid method for this to be realised on these latter 2 levels for those who cannot fathom ajata vada. Upon this realisation it is ‘realised’ there was never a seeker and no real realisation either. Sri Ramana Maharshi explains it more fully here if you are interested.
