योगवासिष्ठः yogavāsiṣṭhaḥ - book-7, chapter-211, verse-17

कार्यकारणभावाच्चेत्कथैवात्र न विद्यते ।
व्योम्नोऽनन्तस्य सिद्धस्य किं कथं किल जायते ॥ १७ ॥

kāryakāraṇabhāvāccetkathaivātra na vidyate ,
vyomno'nantasya siddhasya kiṃ kathaṃ kila jāyate 17

17. There can be no talk of causation, production or vegetation, in the nature of the universe; which being an absolute void, is entirely devoid of the elements of cause and effect.
