In Section 43 of the 'Hadiqat al-Haqiqah', Sanai provides a psychological and ethical critique of cowardice, illustrating how fear undermines human dignity and spiritual progress:

• The Living Hell of Anxiety: Sanai posits that a coward lives in a constant, immediate state of hell (duzakh-e naqd). The continuous dread of future grief and the anticipation of pain are far more agonizing than physical death or wounds suffered in battle.
• The Metaphor of the Deer: He uses the analogy of a deer that eats its food in perpetual fear, which prevents it from growing strong or gaining nourishment. This metaphor represents how fear paralyzes the soul, preventing a person from enjoying life's provisions or realizing their potential.
• Spiritual Incompatibility: Cowardice is depicted as an existential failure. On the path of spiritual struggle, a faint heart (bad-dali) is useless, as spiritual advancement requires the fortitude to face trials and transcend the ego.
