यदानन्द सिन्धौ निमग्नः पुमान्स्यादविद्याविलासः समस्तप्रपञ्चः ।तदा नः स्फुरत्यद्भुतं यन्निमित्तंपरं ब्रह्म नित्यं तदेवाहमस्मि ॥ ८ ॥
In plain words
When a person goes all the way under in the ocean of bliss, and the whole sprawling universe is nothing but the play of ignorance — then something wondrous flashes up in us: the very ground it all stood on. Supreme Brahman, eternal. That alone is what I am.
Close to the Sanskrit
When a person becomes immersed in the ocean of bliss, [and] the entire spread-out universe is [seen to be] the play of ignorance — then there flashes forth for us the wondrous [reality] which is the ground of it: supreme Brahman, eternal; that alone am I.
