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.)
Anandagiri Tika (glossary)
The purpose of the Kārikā is to show that Brahman, birthless and non-dual, is alone existent; for, the waking experiences, on account of their having a beginning and an end, are unreal like the dream ones. Therefore what is seen is Brahman alone. The dream objects are seen within the body; hence they are unreal as things like a mountain, etc., cannot exist within the body. Similarly, all our waking experiences are supposed to be within the body (of the Virāt). Hence they are also illusory from the standpoint of Reality. The Virāt itself is in the Self (Ātman) which cannot, in reality, contain multiplicity. Therefore waking experiences are illusory. The dream experiences are considered illusory as time and space corresponding to such experiences do not conform to the time and space of the dreamer. In like manner waking experiences are also illusory as they, really speaking, cannot exist in the Self (Ātman) which is one, non-dual and homogeneous and which cannot contain any space for the existence of alien objects.
