A discussion of neurological rewiring in the context of meditative practice. 
St. Teresa of Avila suggests prayer and meditation as the door through which one enters the Interior Castle. "The door by which it first enters the castle is prayer and meditation. Once inside,“it must be allowed to roam through these mansions” and “not be compelled to remain for a long time in one single room.” But it must also cultivate self-knowledge and “begin by entering the room where humility is acquired rather than by flying off to the other rooms. For that is the way to progress.”
