Pradhana cannot be the Source - II

I.1.9
स्वाप्ययात् |
Svaapyayaat

On account of  (the individual) merging in one's own self (the self cannot be pradhana)

Svaapyayaat(स्वाप्ययात्) : On account of merging in one's own self

Commentary:
Chhandogya upanishad V1-8-1 says Svam Apita, which means in deep sleep the individual soul resolves in the Sat. The intelligent Self can clearly not resolve itself into the non-intelligent Pradhana. Hence the Pradhana cannot be the First cause denoted by the term 'Sat' in the Brahma Sutra.
