The works of Ādi Śaṅkarācārya

Bṛhadāraṇyakopaniṣadbhāṣyam

Verse 253

मनसैवानुद्रष्टव्यं नेह नानास्ति किंच-न ।मृत्योः स मृत्युमाप्नोति य इह नानेवपश्यति ॥ १९ ॥

In plain words

The mind alone can see it — and here there is no multiplicity at all. Anyone who keeps seeing many things here only travels from one death into another.

Close to the Sanskrit

By the mind alone is it to be perceived: there is no multiplicity here at all. He who sees multiplicity here, as it were, goes from death to death.
