The first Sunday of the month is "Fast Sunday" for LDS members. We traditionally abstain wholly from two meals. There are multiple purposes for this--first, the money saved can be donated to the needy; second, denying oneself in this manner is an exercise in self-control, of spirit over body. This spiritual 'tuning-in' can help us focus our prayers for greater efficacy as well.
During pregnancy and breastfeeding, my body needs the nutrition of not skipping meals. So I have not fasted regularly in years. Although it has been months since my baby started eating enough solid food that I could skip a meal or two, I am simply out of the habit, and usually forget about fasting.
This month, the new moon was on Friday, and I began my fast on Saturday night. For 24 hours I am not eating (I am drinking water for the sake of avoiding dehydration, but only water). In January (right after winter solstice), during my Purification Moon, I cleansed my body by abstaining from sugar for several days. Now, six months later (right after summer solstice) seems a good time to cleanse my spirit. So as I fast, I am praying for spiritual clarity. As we all do from time to time, I have been struggling with some matters of faith in the last few months. So today I put my body under subjection to my spirit, and ask the Divine to help me see things more clearly.
