In the last Section texts of doubtful import were interpreted to refer to Brahman. Some other expressions prescribed for divine contemplation in different Srutis, not already discussed in Section 2 are now taken up for discussion to prove that they all indicate the same Infinite Brahman.

In the First Section of the First Chapter the author (Sutrakara) took up the terms which referred to the manifested world such as Akasa (ether), Prana (energy), Jyoti (light) and showed that they really refer to Brahman. In the Second Section the author took up the terms which referred to the human body and showed that they refer to Brahman. The Section referred to the Saguna aspect of Brahman. The Third Section refers to the Nirguna aspect of Brahman. Here the subject of discussion is to Para Brahman or the Supreme Nirguna Brahman.
