Verse 131

'द्वितीयाद्वै भयं भवति' इति च ।'ज्ञाते त्वात्मनि नास्त्येतत् कार्यकारणतात्मनः' इति च ।'एको देवः सर्वभूतेषु गूढः' इति ।'असङ्गो ह्ययं पुरुषः' इति च ।इत्यादि गौडपादे ।

In plain words

And this: 'Where there is a second, fear begins.' And this: 'Once the Self is known, none of this holds — the Self being cause, the Self being effect.' And: 'One God, hidden in every being.' And: 'This puruṣa touches nothing.' Lines like these, in Gauḍapāda.
