Fasting is not just about giving up food. Done properly in moderation, spiritual fasting will:
• help us understand more about our habits, desires, appetites, and attachments — how they work as well as how to loosen them.
• put us more closely in touch with the inner fullness and contentment that is our radiant spiritual core.
• increase awareness, mindfulness, and restraint.
