The works of Ādi Śaṅkarācārya

Ātmabodhaḥ

Verse 38

एवं निरन्तराभ्यस्ता ब्रह्मैवास्मीति वासना ।हरत्यविद्याविक्षेपान् रोगानिव रसायनम् ॥ ३७ ॥

In plain words

Practiced this way, without a break, the conviction "I am Brahman, and nothing besides" carries off every projection of avidyā — the way a true elixir carries off disease.

Close to the Sanskrit

Thus, the conviction 'I am Brahman alone', practiced without interval, carries away the projections of ignorance, as an elixir carries away diseases.
