Where is the boundary of "I"? This is "No Boundary," a historical masterpiece by Ken Wilber, one of the greatest thinkers of our time, who integrates Eastern wisdom and Western psychology to vividly illuminate the hierarchy of human consciousness.

This book unravels those boundaries one by one and ultimately guides us to a state of "no boundary" consciousness, making it a practical guidebook. • Contents: Translated by Shinitsu Yoshifuku, published by Heibonsha. • Condition: This is a book that has been read and cherished.
