Srimad-Bhagavatam: Canto 6 - Chapter 1 - Verse 23
Sanskrit:
यन्न स्पृशन्ति न विदुर्मनोबुद्धीन्द्रियासव: ।अन्तर्बहिश्च विततं व्योमवत्तन्नतोऽस्म्यहम् ॥ २३ ॥
ITRANS:
yan na spṛśanti na vidurmano-buddhīndriyāsavaḥantar bahiś ca vitataṁvyomavat tan nato ’smy aham
Translation:
The Supreme Brahman emanates from the Supreme Personality of Godhead and expands like the sky. Although untouched by anything material, it exists within and without. Nonetheless, the mind, intelligence, senses and living force can neither touch Him nor know Him. I offer unto Him my respectful obeisances.
