योगवासिष्ठः yogavāsiṣṭhaḥ - book-6, chapter-42, verse-8

तत्त्वसद्रूपमखिलं शून्यवेतालको यथा ।
भ्रमदृष्ट्या तु सद्रूपमित्यहंता जगद्गतिः ॥ ८ ॥

tattvasadrūpamakhilaṃ śūnyavetālako yathā ,
bhramadṛṣṭyā tu sadrūpamityahaṃtā jagadgatiḥ 8

8. akhilam tattva-sad-rūpam śūnya-vetālakaḥ yathā tu
bhrama-dṛṣṭyā sad-rūpam iti ahaṃtā jagad-gatiḥ

8. The entire universe, whose essential nature (tattva) is true reality, appears like a phantom-demon of emptiness (śūnya-vetālakaḥ) – an illusion. However, through delusive perception, it is regarded as truly existing. Thus, the ego-sense (ahaṃtā) itself is the moving force of this world (jagad-gatiḥ).
