योगवासिष्ठः yogavāsiṣṭhaḥ - book-7, chapter-210, verse-32

यथास्थितमिदं विश्वं तथासंस्थमनामयम् ।
ब्रह्मैव निरवद्यात्म चित्संकल्पपुराकृति ॥ ३२ ॥

yathāsthitamidaṃ viśvaṃ tathāsaṃsthamanāmayam ,
brahmaiva niravadyātma citsaṃkalpapurākṛti 32

32. The divine soul is as quiet and unchangeable, as this universe is stable and stationary; and it is the fluctuation of the supreme mind, which causes these variations in the face of the city of the divine will [or the world].
