My Understanding : A person must fulfill their duties consistently. Duties are not limited to one’s job or business; they also include treating others with kindness and avoiding hatred. Strive to be friendly with everyone—even those who consider you an enemy—because their perspective is not your responsibility. Do not become attached to material possessions, as such attachments lead to sorrow. One should remain balanced in all situations, treating happiness and sorrow with equal composure. Avoid pointing out others’ faults and cultivate a forgiving nature. With patience, happiness will find its way to you. In times of joy or sadness, stay steadfast and unwavering in your mind and heart.
