Nineteen Day Feasts: - “to foster comradeship and love, to call God to mind and supplicate Him with contrite hearts, and to encourage benevolent pursuits”

Your detailed letter hath been received, but because of the press of work a brief answer must suffice. You have asked as to the Feast in every Bahá'í month. This Feast is held to foster comradeship and love, to call God to mind and supplicate Him with contrite hearts, and to encourage benevolent pursuits. That is, the friends should there dwell upon God and glorify Him, read the prayers and holy verses, and treat one another with the utmost affection and love. Should trouble arise between two of the friends, let both be invited in, and efforts be made to compose their differences. Let all discussion centre on the doing of charitable acts and holy deeds, that laudable results may be the fruit thereof.
