This wise analogy, attributed to Jesus Christ (PBUH), compares the nature of a mule to that of the human heart. Just as a mule becomes stubborn and difficult when left unworked and unattended, the human heart becomes hard, unyielding, and unresponsive when neglected. The remedy for this hardness is remembering death and performing consistent acts of worship, which soften the heart and maintain its purity and sensitivity.

1. The Necessity of Regular Practice

Jesus (PBUH) highlights that physical and spiritual entities require consistent effort to remain in good condition. Just as a mule needs to be ridden and worked to stay docile and valuable, the heart needs consistent engagement through the remembrance of death and devotion to avoid hardening and becoming neglected.

2. The Importance of Remembering Mortality

Reflecting on death is a powerful tool for spiritual growth and humility. When we remember the inevitability of death, we become more focused on what truly matters: living a righteous life, seeking forgiveness, and appreciating our blessings. This practice humbles the soul, removing arrogance, selfishness, and attachment to materialism — all of which contribute to a hardened heart.

3. The Role of Worship in Softening the Heart

Worship, whether through prayer, meditation, or acts of service, acts as a balm for the human heart. Persevering in prayer helps maintain a connection to the divine, fostering humility, compassion, and spiritual awareness. Without worship, the heart becomes desensitized and distant from the light of faith.

4. The Danger of Neglect

Just as neglecting a mule can lead to destructive behavior, ignoring the heart and soul results in spiritual deterioration. This hardening of the heart leads to a lack of empathy and compassion, and an inability to connect with others and with God. Jesus (PBUH) warns us of this danger and offers a solution: remembrance and worship.

Practical implications:

1. Reflect on mortality. Make time to contemplate the reality of death. This practice is not meant to inspire despair, but rather, to encourage you to live with purpose and focus on what truly matters. It can enable you to prioritize your spiritual health and relationships.

2. Engage in consistent worship. Regular acts of worship — such as prayer, fasting, meditation, and acts of kindness — help keep the heart soft and open to divine guidance. Cultivate a daily habit of connecting with God to maintain spiritual sensitivity.

3. Avoid spiritual neglect. Just as physical exercise keeps the body healthy, spiritual exercise keeps the heart and soul healthy. Avoid long periods of neglect, as this can lead to a hardened heart and drifting away from your faith.

4. Foster gratitude and humility. Remembering death can help you appreciate life's blessings and keep you grounded. Practice gratitude and humility, knowing that life is temporary and true fulfillment lies in a spiritual connection to God.

Conclusion:

Through this profound analogy, Jesus (peace be upon him) reminds us of the fragility of the human heart and the necessity of nurturing it through consistent spiritual practice. Just as a neglected mule becomes stubborn and complex, a heart not softened by the remembrance of mortality and sustained by worship can harden and become unresponsive. This saying encourages us to prioritize our spiritual well-being by staying connected to the divine, reflecting on the transient nature of life, and remaining steadfast in acts of worship and devotion.
