Which spiritual discipline involves refraining from food?

Fasting is a spiritual discipline that specifically involves refraining from food for a certain period. This practice is often undertaken for spiritual growth, to seek God's guidance, or to enhance prayer life. It allows individuals to focus on their relationship with God while expressing dependence on Him. During fasting, believers may use the time usually spent on meals for prayer and reflection, thus deepening their spiritual connection. This act can also serve as a form of humility and repentance, aligning one's heart and mind with God's will. The other options, such as prayer, confession, and meditation, do not involve the physical act of abstaining from food but rather focus on communication with God, acknowledgment of sins, and contemplative practice, respectively.
