I am interested in reading about fasting as a spiritual discipline and/or religious requirement in the Abrahamic faith traditions. I would like to look at classical/traditional works as well as those by contemporary practitioners. I am purposely casting a wide net because I am only at the beginning of this exploration.
At this stage I only have read The Inner Dimensions of Fasting by Abu Hamid al-Ghazali.
thank you for any reading suggestions.
