योगवासिष्ठः yogavāsiṣṭhaḥ - book-7, chapter-167, verse-24

संविच्च चिन्नभोमज्जा सैवंरूपैव सर्वदा ।
नास्तमेति न चोदेति तस्याः स्वाङ्गमिदं जगत् ॥ २४ ॥

saṃvicca cinnabhomajjā saivaṃrūpaiva sarvadā ,
nāstameti na codeti tasyāḥ svāṅgamidaṃ jagat 24

24. Consciousness is the pith and marrow of vacuous Intellect, and retains this form (of its quiddity) at all times; it neither rises nor sets, and this world is inherent in it.
