Letter to Editor: A Comprehensive Definition of Spiritual Health

Spirituality is recognized globally as an important aspect to respond to many  questions associated with health and happiness. The World Health Organization is also interested in pursuing the physical, psychological, and social dimensions of health (1).
There are several challenges regarding the definition of spiritual health and the advancement of research in this regard (2). In addition, due to the controversies, it is difficult to achieve a common definition of spirituality (3, 4).
However, it seems that the current definitions (5) on the concepts and indicators of spiritual health do not provide comprehensive coverage of all factors in societies; therefore, the results obtained from spiritual health research in one society are not generalizable to different societies.
Furthermore, due to the differences in people's attitudes towards religion and spirituality, it is difficult to evaluate these concepts independently or in combination. As we know, the cognition, actions, emotions, and personal effects of individuals are important indicators of spirituality.
