“Ignorance is the cause of bondage; knowledge of the self is liberation.”
— ShankaraParaphrase of the teaching in the Vivekachudamani (attributed to Shankara); exact wording varies by translation

Commentary

Liberation (moksha), for Shankara, consists in discerning the true self beyond the superimposition of body and mind. The statement is a paraphrase, so consult a specific translation for precise wording.
