What is the state he says to go into?

​It is the Theta State of Mind. In theta state your brainwave frequency is much lower i.e., 4 Hz - 7.5 Hz. It is the state which you achieve just before you go into a deep sleep. In this state you have the ability to write and delete anything from the subconscious mind. Basically, this is the method to reach the subconscious level to change the belief system which is necessary for the law of attraction to work.
