HEART MAXIMS: The Mutual Influence of Bodily Acts and the Heart: An Islamic and Psychological Perspective

Courses

Classical Islamic scholarship has long emphasised the intricate relationship between the heart (qalb) and the body (jawariḥ), suggesting that one’s inner spiritual state and outward physical actions mutually influence one another. The principle that bodily acts influence the heart occupies a central place in classical Islamic thought. The 14th-century scholar Ibn Taymiyyah (d. 1328) wrote, “What occurs in the body through words and actions also affects what is in the heart; each of them influences the other. But the heart is the origin and the body its branch. The branch draws from its origin, and the origin is strengthened and stabilised through its branch” (Majmuʿ al-Fatawa, 7/541). His student Ibn al-Qayyim (d. 1350) elaborated this dynamic, asserting that physical obedience purifies the heart, while sin and heedlessness darken it.

This reciprocal model challenges the reductionist view that morality or spirituality originates solely within the inner self. Instead, it proposes a cyclical process: the heart inspires righteous action, and those actions, in turn, refine and fortify the heart. The Qur’an itself echoes this concept: “O you who have believed, decreed upon you is fasting as it was decreed upon those before you, that you may become righteous” (Q 2:183). Here, a bodily act-fasting-becomes a means for cultivating piety, demonstrating that physical discipline can transform the inner moral landscape.


Contemporary psychology increasingly affirms what these scholars intuited centuries ago: cognition and emotion are not confined to the brain but are embodied processes shaped by physical experience. Gallagher (2023) describes cognition as “enactive”-arising through dynamic interactions between body, environment, and consciousness. Recent educational and neuroscientific research shows that bodily activity such as gesture, movement, or sensory engagement enhances understanding and emotional regulation (Zeng et al., 2024).

The parallels with Islamic teachings are striking. When a believer engages the body in worship-standing, bowing, and prostrating-the act itself becomes a form of embodied cognition, reinforcing humility, focus, and devotion. Such rituals do not merely symbolise faith; they cultivate it. This aligns with empirical findings that intentional physical postures can influence emotional states, suggesting that bodily discipline, far from being a peripheral aspect of spirituality, is essential to its development.

Modern clinical psychology offers further evidence through the theory of behavioural activation (BA), a intervention for ‘depression’ and emotional dysregulation. The central premise of BA is that deliberate engagement in meaningful activity-even when motivation is absent-can restore emotional vitality. Takagaki and Yokoyama (2024) found that avoidance behaviour among university students predicted greater depressive symptoms, while consistent engagement in purposeful actions mediated recovery. Similarly, Alber et al. (2023) demonstrated that online behavioural activation programs significantly reduced depressive symptoms across populations.


This modern framework mirrors Ibn Taymiyyah’s spiritual psychology. Just as behavioural activation teaches that “doing” precedes “feeling,” Ibn Taymiyyah asserted that bodily obedience nourishes and strengthens the heart. The act of prayer, charity, or fasting can precede and produce sincere emotion, not merely express it. Both traditions converge on the insight that right action can generate right feeling-that discipline precedes delight, and obedience cultivates inner peace.

 

Gaze Regulation and the Psychology of Attention

Ibn al-Qayyim dedicated an entire chapter to the effects of ghaḍ al-naẓar (lowering the gaze) on the heart, describing how refraining from forbidden sights “brings intimacy to the heart, strengthens it, and grants insight.” Contemporary psychological research on gaze control supports these claims. Han and Eckstein (2023) demonstrated that intentional control of eye movements enhances inferential and attentional processes. Similarly, studies on social anxiety reveal that gaze aversion and visual focus directly modulate emotional arousal and self-regulation (University of Leiden, 2023).

In essence, how one directs physical attention-where one looks-shapes internal experience. By consciously regulating gaze, individuals practice attentional discipline, cultivating emotional composure and moral awareness. Concept of spiritual firasah (insight) aligns with this: purified perception arises not only from intellectual reflection but from embodied restraint.

Taken together, these perspectives illustrate a profound harmony between Islamic spiritual psychology and sound contemporary empirical science. Both propose a bi-directional model of human transformation: the inner self shapes bodily behaviour, and bodily behaviour refines the inner self. Fasting, prayer, and gaze regulation, as described in Islamic texts, find modern analogues in behavioural activation, mindfulness, and attentional training.

Recent neuroscience and embodied cognition research further affirm that repeated physical actions can rewire neural pathways and emotional responses (Tang et al., 2023). This suggests that spiritual practices, far from being mere symbolic gestures, engage neurobiological systems that shape resilience, compassion, and self-control. The believer’s journey, then, becomes both a spiritual and physiological process-a feedback loop between action and heart.
