योगवासिष्ठः yogavāsiṣṭhaḥ - book-7, chapter-41, verse-23

ब्रह्मैव शान्तिघनभावगतं विभाति सर्गोदयेन विगतास्तमयोदयेन ।
व्योमेव शून्यविभवेन गलत्स्वभावलाभं प्रति प्रसभमेव ननु प्रबुद्धे ॥ २३ ॥

brahmaiva śāntighanabhāvagataṃ vibhāti sargodayena vigatāstamayodayena ,
vyomeva śūnyavibhavena galatsvabhāvalābhaṃ prati prasabhameva nanu prabuddhe 23

23. Brahma is seated in his impenetrable tranquillity and in the form of the rising world, with ever rising or setting himself; He is as free and void as vacuity and without any nature or property of his own, and is known to the enlightened understanding.
