योगवासिष्ठः yogavāsiṣṭhaḥ - book-6, chapter-56, verse-18

अतः कालक्रियाकुड्यकलादिविमलं नभः ।
चित्तसंस्थं यथा चित्रं सरूपमखिलात्मकम् ॥ १८ ॥

ataḥ kālakriyākuḍyakalādivimalaṃ nabhaḥ ,
cittasaṃsthaṃ yathā citraṃ sarūpamakhilātmakam 18

18. ataḥ kāla-kriyā-kuḍya-kala-ādi-vimalam nabhaḥ |
citta-saṃstham yathā citram sa-rūpam akhila-ātmakam ||

18. ataḥ nabhaḥ kāla-kriyā-kuḍya-kala-ādi-vimalam (asti)
yathā citta-saṃstham citram sa-rūpam akhila-ātmakam (asti)

18. Therefore, space (nabhaḥ) is pure, free from (the limitations of) time, activity, limiting boundaries (kuḍya), distinctions (kalā), and so forth. It is like a picture residing in the mind (cittasaṃstham) which, though appearing with specific forms (sarūpam), is in its essence all-pervading (akhilātmakam) consciousness.
