योगवासिष्ठः yogavāsiṣṭhaḥ - book-7, chapter-210, verse-35

तदेवेत्थं परिज्ञातं ब्रह्मतामुपगच्छति ।
यदा तेन समं विश्वं स्थितमेव विलीयते ॥ ३५ ॥

tadevetthaṃ parijñātaṃ brahmatāmupagacchati ,
yadā tena samaṃ viśvaṃ sthitameva vilīyate 35

35. This being confessed it becomes evident, that the world is the deity itself; and when the world appears as one with the deity, it is seen in our clairvoyance to be extinct in the Divine essence.
