It is true you cannot enter all the mansions by your own power, however great it may appear to you, unless the Lord of the castle Himself admits you. Therefore I advise you to use no violence if you meet with any obstacle, for that would displease Him so much that He would never give you admission to them. He dearly loves humility: if you think yourselves unworthy to enter the third mansion, He will grant you all the sooner the favour of entering the fifth.
– St. Teresa of Avila
