Humans have a unique intelligence known as spiritual intelligence that tends to seek meaning and purpose in their lives, ask questions about one's existence, and render resolute conclusions to one's actions. Today, school teachings align with the industry's demands and are nurturing students' cognitive attributes. As the demand for technological innovations increases, the demand for focusing on vocational skill-focused education is also increasing. However, in the era of rapid technological innovations, nurturing the men's psyche behind the technology-driven progress is equally important. The chapter discusses the relevance of spiritual intelligence in schools. Further, the chapter explores spiritual intelligence's relationship with psychological wellbeing, mental health, quality of life (QOL), happiness, and academic performance. The way forward measures to enhance students' spiritual intelligence are also discussed for achieving students' holistic development.
