योगवासिष्ठः yogavāsiṣṭhaḥ - book-7, chapter-167, verse-14

निर्निमित्तं स्वरूपात्म तदेतत्परमात्मनि ।
सर्वात्मन्यपि निर्वाणे व्योमात्मनि निरात्मनि ॥ १४ ॥

nirnimittaṃ svarūpātma tadetatparamātmani ,
sarvātmanyapi nirvāṇe vyomātmani nirātmani 14

14. The uncaused world, exists of itself in the Supreme soul; and becomes extinct of itself, in the vacuity of the universal soul.
