Now Yama organizes the bodily functions in a hierarchy. He says, “Higher than the senses are the sense objects. Higher than the sense objects is the mind. Reason or buddhi is higher than the mind. The mahat or awareness is higher than buddhi. Higher than the mahat is avyakta, undifferentiated nature. The infinite Self, purusa is greater than avyakta and the purusa is the supreme goal. There is nothing higher than This.”
Purusa is an alternate name for Brahman or Atman.
