Essentially, it means to feel and to visualize yourself in that state before actually doing anything. Most people live life by doing actions to become who they are, but if "be" that person first you'll set the stage (and the universe in motion) to do the actions in the future. You need to let go of thoughts that inhibit this success. If you read the SOGR, you'll sort of see how this applies. LSC does a great job with this in the Ideal Mindset personal learning course and in the NB book.
