रज्जुसर्पवदात्मानं जीवं ज्ञात्वा भयं वहेत् ।नाहं जीवः परात्मेति ज्ञातं चेन्निर्भयो भवेत् ॥ २७ ॥
In plain words
Mistake a rope for a snake and you flinch. Mistake the Self for the jīva — this small, separate person — and you carry fear everywhere you go. But once it is truly known, I am not the jīva, I am the supreme Self, you are fearless.
Close to the Sanskrit
Like the rope as a snake, having known the Self as the jīva, one would carry fear. If it is known, 'I am not the jīva, I am the supreme Self,' one would become fearless.
