As regards the questions of tribal practice, the Guardian wishes you to be extremely forbearing and patient in weaning the Bahá'ís away from their old customs. This can only be done by taking each case individually as it comes up, using the greatest wisdom and kindness, and not trying rigorously to impose all Bahá'í laws in every detail at this time.
