Verse 34

अयं सोऽहमिदं तन्म इति मज्जति नात्मवान् ।अयं सोऽहमिदं तन्म इति मज्जत्यनात्मवान्

In plain words

'This one am I, that one am I; this is mine, that is mine' -- thinking so, one possessed of the Self does not sink. 'This one am I, that one am I; this is mine, that is mine' -- thinking so, one without the Self sinks.
