Viṣṇusahasranāmastotram

Verse 121

निश्चरन्ति यथा लोहपिण्डात्तप्तात्स्फुलिङ्गकाः ।सकाशादात्मनस्तद्वत्प्रभवन्ति जगन्ति हि ॥

In plain words

Just as countless sparks fly out from a blazing ball of hot iron, so do all the worlds emerge directly from the Supreme Self.

Close to the Sanskrit

Just as sparks issue forth from a heated iron ball, similarly from the presence of the Self do the worlds indeed originate.
