When one learns non-identification, then life becomes a teacher. In both pleasant and unpleasant situations of life, can one remain without attachment? It is not just life that is a teacher, but life without attachment that is a real teacher.
Non-identification leads to detachment, which transforms our unexciting life into an exciting learning experience.
Identification leads to loss of objectivity. In such a state we cannot see what is as it really is. Through identification, we superimpose our subjective perceptions on the object. We get identified with the percept and lose objective perception.
