योगवासिष्ठः yogavāsiṣṭhaḥ - book-7, chapter-63, verse-9

श्रीराम उवाच ।
भगवन्स्वप्न एवेदं कथं जाग्रदवस्थितम् ।
असत्यमेव सत्यत्वमिव यातं कथं भवेत् ॥ ९ ॥

śrīrāma uvāca ,
bhagavansvapna evedaṃ kathaṃ jāgradavasthitam ,
asatyameva satyatvamiva yātaṃ kathaṃ bhavet 9

9. Rama rejoined:—Sir, if these be but dreams, how is it they appear to us in our waking state; and if they are unreal, why is it that they seem as solid realities unto us?
