Advaita Vedanta's classical texts are explicit that savikalpa samadhi, however profound its bliss and however transformative its effect on the practitioner, does not by itself constitute liberation, moksha, because liberation in the Advaita system requires the direct, unmediated realization that the individual self, atman, and ultimate reality, Brahman, are not two, a realization the tradition holds must be permanent and available even outside formal meditative states, not confined to the temporary altered condition of samadhi.
A practitioner can enter and leave savikalpa samadhi repeatedly across years of practice without achieving this permanent realization, which is why teachers in this tradition treat the state as a way station, valuable evidence of real spiritual progress and a powerful support for further practice, rather than as the destination itself. This distinction between a temporary, if extraordinary, meditative state and a permanent change in self understanding is one of the more carefully guarded points in Advaita pedagogy, meant to prevent students from mistaking an intense experience, however genuine, for the completed realization the tradition considers its actual goal.
