"Beyond Personality" is one of the chapters in C.S. Lewis's book "Mere Christianity." In this section, Lewis explores the idea of moving beyond mere personality to a deeper understanding of spirituality and the Christian concept of God. The chapter discusses the nature of God as it relates to the Trinity—Father, Son, and Holy Spirit—and the implications of this understanding for Christian belief.

"Mere Christianity" is a classic work that originated as a series of radio broadcasts during World War II. It provides a reasoned defense of Christian beliefs and explores the common ground shared by Christians across denominational lines. "Beyond Personality" is a significant part of this exploration, delving into theological concepts that go beyond our limited human understanding of personality and identity.
