The focus of this article is a conceptualisation of the spiritual life dimension of the human being. The central perspective or approach is the Personal, Interpersonal and Professional Leadership (PiPL) perspective developed by Smith. PiPL is a holistic wellness perspective that includes the personal, interpersonal and professional contexts of the individual’s life, and considers the anthropological characteristics, existential realities and phenomenology that humankind is faced with. PiPL views the spiritual life dimension as the core of being human. In this article Smith’s PiPL perspective of the nature and manifestations of the spiritual life dimension in the existential world will be explored.
