Gumonji is a Shingon Buddhist practice that is easy to explain, difficult to imagine, and nearly impossible to carry out. You still want to try it? Well, OK.

In simple terms, gumonji requires one to recite the Mantra of the Buddhist deity Kokuzo Bosatsu 1 million times. Kokuzo is the "Great Space Bearer," because he holds the wisdom of the Buddha throughout the entire universe. He is pictured holding a gem in which he bestows his worldly blessings.

The Kokuzo mantra goes like this: "Nobo akyasha-kyarabaya om arikya mari bori sowaka." The translation is: "In the name of Kokuzo Om Flower-Garland Lotus-Crown may it be accomplished." It's not that long, but how long would it take to recite it one million times?
