Einstein is speaking to proper alignment within the Immanent Holarchy of the Spirit -> Soul -> Personality.

Your agency is your self. Your Body/Mind.

Your True Identity is All of Existence. 

Your Task is to over come the persistent illusory prison that you are your Body/Mind.

Your Process is recognizing all the energetic Self-contractions that manifest as limiting beliefs, unresolved traumas, and negative emotions like fear, uncertainty and doubt that stand between you and Identifying as All of Existence.

It is here where unending Liberation and Positive Flourishing is found.
