The critical review of the literature describes the definition clarity of spirituality, religion, and faith. These three terms are interchangeably used in the literature. However, each of these terms has its own definitions. For example, the term spirituality has more than 13 conceptual components. It is abstract and subjective and is different from religion and faith. Spirituality can be a connection to God, nature, others, and surrounding. Spirituality is associated with quality and meaning in life. Conversely, religion is attributed to traditional values and practices related to a certain group of people or faith. Religion is guided by tradition, rules, and culture. Religion is defined as a personal set or institutionalized system of religious attitudes, beliefs, and practices. Religion is the service or worship of God or the supernatural. Faith is often associated with religion and spirituality. Faith is more personal, subjective, and deeper than organized religion and relates to the relationship with God. The concept of spirituality lacks a professional understanding. It is imperative that the holistic view of nursing must strive to understand the definition of spirituality.
