This period coincides with the Bahá'í month of Ala (meaning Loftiness), from March 2-20, inclusive. This is the month immediately preceding the Bahá'í new year, which occurs the day of the vernal equinox; and the period of fasting is therefore viewed as a time of spiritual preparation and regeneration for a new year's activities. Women who are nursing or pregnant, the aged, the sick, the traveler, those engaged in heavy labor, as well as children under the age of 15, are exempt from observance of the fast. The fasting period, which lasts nineteen days starting as a rule from the second of March every year and ending on the twentieth of the same month, involves complete abstention from food and drink from sunrise till sunset. It is essentially a period of meditation and prayer, of spiritual recuperation, during which the believer must strive to make the necessary readjustments in his inner life, and to refresh and reinvigorate the spiritual forces latent in his soul. Its significance and purpose are, therefore, fundamentally spiritual in character. Fasting is symbolic, and a reminder of abstinence from selfish and carnal desires.
