Mandukya Karika, verse 4.33

Text

सर्वे धर्मा मृषा स्वप्ने कायस्यान्तनिदर्शनात् ।
संवृत्तेऽस्मिन्प्रदेशे वै भूतानां दर्शनं कुतः ॥ ३३ ॥

sarve dharmā mṛṣā svapne kāyasyāntanidarśanāt |
saṃvṛtte'sminpradeśe vai bhūtānāṃ darśanaṃ kutaḥ || 33 ||

33. All objects cognised in dream are unreal, because they are seen within the body. How is it possible for things, that are perceived to exist, to be really in Brahman which is indivisible and homogeneous.

Shankara Bhashya (commentary)

This and the following verses are meant to explain in detail one of the previous Kārikās which states that the (so-called) cause (of the opponent) is, really speaking, no cause at all. (Ref. Verse 25, Chapt. IV.)
