Summary
This quote suggests that it is incredibly easy for individuals to deceive others and themselves by pretending to have a deep understanding or perception of things that may not truly exist. The concept of an "inner vision" refers to one's personal insights, ideas, and outlook on life. However, since this vision is not externally visible or tangible, it can be easily fabricated or misrepresented. Therefore, the quote serves as a reminder to be cautious, as people may feign wisdom or understanding, masking their true intentions.
