As regards various matters you raised in your letters, the reason we commemorate the 1st, 9th and 12th days of Ridvan as Holidays (Holy Days) is because one is the first day, one is the last day, and the third one is the ninth day, which of course is associated with the number 9. All 12 days could not be holidays, therefore these three were chosen. (Letter written on behalf of the Guardian, dated June 8, 1952, to an individual believer, in Lights of Guidance)
