Which one of the following advice an existantialist teacher did not offer to his/her students ?

An Existentialist teacher encourages students to engage in concrete self-analysis, make authentic personal choices, and confront human suffering and anguish for personal growth. 'Listening to the voice of your inner self' (the eternal spiritual soul or Antaratma) is a classic Idealist and Vedantic injunction rather than an Existentialist one.
