Vasiṣṭha's teaching (Mahārāmāyaṇa) 6.28.58

6.28.58

idaṃ hi jagatāṃ jālaṃ kimatra paridevanā .
satsadeva sadaivaitadasadevāsadeva hi .. 58

58. [Sanskrit available] These spheres of worlds enlarge, expand and rise to our view, like bubbles of water in the sea which swell and float and shine for a time, and then burst and subside in the water of eternity.

59. [Sanskrit available] The nature of reality (the entity of Brahma), is real at all times, and the condition of the unreal world is unsubstantial for ever, and can never be otherwise or real, though it may? appear as such for a time. Why then sorrow for what is nil and unreal.
