This work investigates the potential for a constructive synthesis between scientific inquiry and religious experience by examining the psychological nature of peak-experiences. Abraham H. Maslow, a foundational figure in humanistic psychology, utilizes his research on self-actualization to argue that religious phenomena can be studied empirically. He posits that the core of religious life is rooted in the subjective, transcendent moments he terms peak-experiences, which are accessible to individuals regardless of traditional theological frameworks.

Psychologists and philosophers frequently cite this text as a significant contribution to the study of humanistic spirituality and the psychology of religion. Readers often note the accessible yet rigorous nature of Maslow's prose as he bridges the gap between empirical observation and subjective experience.
