योगवासिष्ठः yogavāsiṣṭhaḥ - book-6, chapter-95, verse-18

अकार्यत्वाच्च नास्त्येतत्सर्ग इत्थं न विद्यते ।
यदा न कस्यचित्कार्यं कारणस्य जगत्तदा ॥ १८ ॥

akāryatvācca nāstyetatsarga itthaṃ na vidyate ,
yadā na kasyacitkāryaṃ kāraṇasya jagattadā 18

18. akāryatvāt ca na asti etat sargaḥ ittham na vidyate
yadā na kasyacit kāryam kāraṇasya jagat tadā

18. etat sargaḥ akāryatvāt ca na asti ittham na vidyate.
yadā kasyacit kāraṇasya kāryam na tadā jagat

18. And because this (apparent) creation (sarga) is not an effect (akārya), it does not truly exist; thus, it is not perceived in this manner. When there is no effect (kārya) of any cause, then the world (jagat) [itself does not exist].
