Seokmun Hoheup is one’s Brightness.

This Brightness is Light, and the Light is the path(도/道/Do) that
guides one toward Their Essential Self. Through the publication
of this book on Seokmun Hoheup, I present the 15–level
practice process to all those who, even at this very moment,
devote themselves with wholehearted passion to the journey
of self-inquiry, asking the timeless question: “Who am I?”
I sincerely hope that many will find Their Essential Selves
through the practice of Seokmun Hoheup.
