A fallow mind is a field of discontent.
A vacant or unengaged mind often leads to dissatisfaction and unrest, as it lacks purpose and stimulation. When the mind is idle or unfocused, it becomes prone to negative thoughts and feelings of discontent, highlighting the importance of mental activity and engagement.
According to John H. Cunningham in his book Red Right Return, a fallow or unproductive mind creates a fertile ground for discontentment. This suggests that nurturing the mind with meaningful pursuits and thoughts is essential for inner peace and satisfaction.
