With the words 'Leave the mirror and change your face. Leave the world alone and change your conceptions of yourself' Goddard invites us to resist the temptation toward judgment and to look at ourselves for the change we want to see in the world an in others. 'God's promise is unconditional'.
You rise to a higher level of consciousness by taking your attention away from your present limitations and placing it upon that which you desire to be. Do not attempt this in day-dreaming or wishful thinking but in a positive manner. Claim yourself to be the thing desired. I AM that; no sacrifice, no diet, no human tricks. All that is asked of you is to accept your desire. If you dare claim it, you will express it.
'Leave all and follow me' is a double invitation to you. First, it invites you to turn completely away from all problems and, then, it calls upon you to continue walking in the claim that you are that which you desire to be.
Do this and you will know that you have found the master, the Master Magician, making the unseen the seen through the command: I AM THAT!
