The document explores the question of personal identity and what constitutes the self. It argues that concepts like "I", "you", and "we" do not represent a permanent or unchanging essence, but rather refer to ever-changing physical and mental processes dependent on conditions.

Ultimately, there is no fixed or absolute self; reality exists beyond labels and concepts. True enlightenment involves seeing all things as they are without subjective perceptions or clinging to preconceptions.
