The spiritual dimension is the most important aspect of human health. In religious teachings, knowledge and faith in God, along with righteous actions, are considered the main pillars of spiritual health. The present research aimed to to conduct a comparative study of spiritual health from the perspectives of Zakariya Razi, Polotzin, and Allison. The method of this research is library-based, involving the collection of information through note-taking from reference books, articles, and credible manuscripts. The results indicated that Zakariya Razi describes the governance of reason over other faculties, the struggle against desires, and the purification of the soul from moral vices, such as envy, greed, and arrogance as signs of a healthy soul. Polotzin and Allison define spiritual health as possessing a sense of acceptance, positive emotions, ethics, and positive reciprocal connection with a higher divine power, others, and oneself. The spiritual health of each individual depends on the quality of their understanding and perspective regarding themselves, the universe, and the divine forces governing creation. This concept has a specific relationship with the ethical realm in Zakariya Razi's view to such an extent that sometimes distinguishing it from moral action is difficult. In his perspective, a healthy individual or one possessing spiritual health is essentially an ethical person; that is to say, someone who has an optimal moral performance. Nonetheless, from Polotzin and Allison's viewpoint, the concept and scope of spiritual health and a healthy individual are broader than moral health; they also encompass social, cultural factors and individual personality structures, making their perspective more comprehensive and realistic compared to Razi's perspective.
