At twenty-five, activist Cristina Moon faced an impossible task: preparing for the possibility of arrest and torture inside military-ruled Myanmar. Her response? Learning Buddhist meditation. So began what would become a decades-long spiritual path-eventually leading her to a Zen temple and martial arts dojo in Hawai'i with a timeless method of warrior Zen training. Offering a bracing account of three years of mind-body-spirit training at Daihonzan Chozen-ji, a Rinzai Zen temple and martial arts dojo, Moon powerfully captures the rigors and realizations that finally shaped her into a Zen priest whose highest directive is to give fearlessness. Told with immersive detail and an unique Asian American female perspective, Three Years on the Great Mountain chronicles Moon's straight-up-the-mountain training regimen at Chozen-ji, conducted every day and often through the nights. Through the spiritual forging of daily Zen meditation, manual labor, swordsmanship, and Japanese tea ceremony, she discovers a newfound conviction that self mastery and spiritual growth can take fierce form. Embraced by local Hawai'i and Japanese culture, and a community of discipline, respect, and discovery, she discovers a profound sense of home.
