This book is an in-depth, critical and spiritual guide to the transit of Saturn through the sign of Aries between 2025 and 2028. Its pages explore the personal and collective challenges that this transit activates: the fear of starting, the redefinition of leadership, discipline versus impulse, and the conscious management of anger. Saturn -the master of time and responsibility- enters the warrior's terrain to test his maturity, authenticity and capacity for action.
