7 When Paula comes to be a little older and to increase like her Spouse in wisdom and stature and in favour with God and man, let her go with her parents to the temple of her true Father but let her not come out of the temple with them. Let them seek her upon the world's highway amid the crowds and the throng of their kinsfolk, and let them find her nowhere but in the shrine of the scriptures, questioning the prophets and the apostles on the meaning of that spiritual marriage to which she is vowed.
Let her imitate the retirement of Mary whom Gabriel found alone in her chamber and who was frightened, it would appear, by seeing a man there. Let the child emulate her of whom it is written that “the king's daughter is all glorious within.” Wounded with love's arrow let her say to her beloved, “the king has brought me into his chambers.” At no time let her go abroad, lest the watchmen find her that go about the city, and lest they smite and wound her and take away from her the veil of her chastity, and leave her naked in her blood. Nay rather when one knocks at her door let her say: “I am a wall and my breasts like towers. I have washed my feet; how shall I defile them?”
