A masterwork from the world's greatest Jiu Jitsu fighter and international bestselling author of BREATHE. A mythic figure in fighting and a legendary member of the "first family of martial arts," Rickson Gracie is considered the godfather of what we recognize today as Mixed Martial Arts (MMA). Although Rickson's three decades of total dominance in Jiu Jitsu is astounding, even more astounding is the serenity and spiritual depth of his approach to combat. Some consider Jiu Jitsu a martial art, others consider it a sport, but to Gracie, it is a philosophical system he uses to face and evaluate life's challenges and maintain happiness and peace of mind.

Gracie wrote Comfort in Darkness after being diagnosed with Parkinson's Disease, a terminal sentence which he views as the greatest fight of his life, one he knows he will eventually lose. This is Gracie's defining life statement about his spiritual and technical practice. For the first time, he reveals his time-tested theories and techniques of invisible Jiu Jitsu, a combat system anyone can use to awaken their power and apply it to their everyday lives. An indispensable tool for any fighter or seeker, Comfort in Darkness teaches how to balance and align the mind, body, and spirit.
