आभातीदं विश्वमात्मन्यसत्यम्सत्यज्ञानानन्दरूपे विमोहात् ।निद्रामोहात्स्वप्नवत्तन्न सत्यम्शुद्धः पूर्णो नित्य एकः शिवोऽहम् ॥ ३ ॥
In plain words
This whole universe shines out in the Self, and it is not real. It shines in that Self whose very nature is being, awareness, bliss — and it shines only out of delusion. Like a dream thrown up by the confusion of sleep, it is not real. Pure, whole, eternal, one — I am Śiva.
Close to the Sanskrit
This universe, unreal, appears in the Self — whose nature is being, awareness, bliss — through delusion. Like a dream arising from the confusion of sleep, it is not real. Pure, whole, eternal, one — I am Śiva.
