Who can free you of your past, personal and social, except yourself?

Q: You seem to drive me always back into myself. Is there no objective solution to the world's problems?
M: The world problems were created by numberless people like you, each full of his own desires and fears. Who can free you of your past, personal and social, except yourself? And how will you do it unless you see the urgent need of your being first free of cravings born of illusion? How can you truly help, as long as you need help yourself?
