योगवासिष्ठः yogavāsiṣṭhaḥ - book-7, chapter-204, verse-18

द्रवत्वादम्बु हृद्याब्धेर्नानावृत्तितया यथा ।
अनानैव भवेन्नाना चिद्व्योमात्मनि वै तथा ॥ १८ ॥

dravatvādambu hṛdyābdhernānāvṛttitayā yathā ,
anānaiva bhavennānā cidvyomātmani vai tathā 18

18. dravatvāt ambu hṛdi abdheḥ nānā-vṛttitayā yathā
anānā eva bhavet nānā cit-vyoma ātmani vai tathā

18. yathā hṛdi abdheḥ ambu dravatvāt nānā-vṛttitayā anānā eva nānā bhavet.
tathā vai cit-vyoma ātmani nānā anānā eva bhavet

18. Just as water (ambu), by its intrinsic fluid nature (dravatva), though appearing in various forms (nānāvṛttitayā) from the ocean (abdhī) of the heart (hṛd), is actually non-diverse (anānā eva) even while manifesting as diversity (nānā); similarly, in the consciousness-space (cit-vyoma) that is the Self (ātman), diversity (nānā) indeed arises, yet it remains essentially non-diverse (anānā eva).
