9.2.p6

The Bhagavān told them, “There is a devoted laywoman who instructs her daughter, ‘While you’re living at home, you should be like the laywomen Kubjottarā or Nanda’s mother. Why is that? They are your standard; they are your measure. The Bhagavān accepted the realization of these disciples, the laywomen Kubjottarā and Nanda’s mother.’ If her daughter decides to cut off her hair, put on the three Dharma robes, leave home, and train on the path, she should be like the nuns Kṣemā and Utpalavarṇā. Why is that? Then, the nuns Kṣemā and Utpalavarṇā would be her standard; they would be her measure.
