Hakuin Ekaku (1686–1769 or 1685–1768) was one of the most influential figures in Japanese Zen Buddhism. He revived the Rinzai school from a moribund period of stagnation, refocusing it on its traditionally rigorous training methods integrating meditation and koan practice. Hakuin's
Hakuin was born in 1686 in the small village of Hara, at the foot of Mount Fuji. His mother was a devout Nichiren Buddhist, and it is likely that her piety was a major influence on his decision to become a Buddhist monk. As a child, Hakuin attended a lecture by a Nichiren monk on the topic of the Eight Hot Hells. This deeply impressed the young Hakuin, and he developed a pressing fear of hell, seeking a way to
escape it. He eventually came to the conclusion that it would be necessary to become a monk. At the age of fifteen, he obtained consent from his parents to join the monastic life, and was ordained at the local Zen temple, Shoin-ji. When the head monk at Shoin-ji took ill, Hakuin was sent to a neighboring temple, Daisho-ji, where he served as a novice for three or four years, studying Buddhist texts.
While at Daisho-ji, he read the Lotus Sutra, considered by the Nichiren sect to be the king of all Buddhist sutras, and found it disappointing, saying "it consisted of nothing more than simple tales about cause and effect". At the age of nineteen, he came across in his studies the story of the Chinese Ch'an master Yantou Quanhuo, who had been brutally murdered by bandits.
Hakuin despaired over this story, as it showed that even a great monk could not be saved from a bloody death in this life. How then could he, just a simple monk, hope to be saved from the tortures of hell in the next life? He gave up his goal of becoming an enlightened monk, and not wanting to return home in shame, traveled around studying literature and poetry. While studying with the poet-monk
Bao, he had an experience that put him back along the path of monasticism. He saw a number of books piled out in the temple courtyard, books from every school of Buddhism. Struck by the sight of all these volumes of literature, Hakuin prayed to the gods of the Dharma to help him choose a path. He then reached out and took a book; it was a collection of Zen stories from the Ming Dynasty.
Inspired by this, he repented and dedicated himself to the practice of Zen. He again went traveling for two years, settling down at the Eigan-ji temple. It was here that Hakuin had his first experience of enlightenment. He locked himself away in a shrine in the temple for seven days, and eventually reached what he believed to be an intense awakening upon hearing the ringing of the temple bell. However, his master
refused to acknowledge this enlightenment, and Hakuin left the temple. After leaving Eigan-ji, Hakuin met and studied with the teacher who would be most influential on his spiritual practice, Shoju Ronin. Shoju was an intensely demanding teacher, who hurled insults and blows at Hakuin, in an attempt to get him to reach satori. After several more experiences of enlightenment, Hakuin left Shoju after
eight months of study. Though he never saw Shoju again, and the master would die thirteen years later, Hakuin would continue to think of Shoju as his primary master. After another several years of travel, at age 31 Hakuin returned to Shoin-ji, the temple where he had been ordained.
He was soon installed as abbot, a capacity in which he would serve for the next half-century. It was around this time that he adopted the name "Hakuin", which means "concealed in white", referring to the location of Shoin-ji temple. At age 41, he experienced a final and total experience of enlightenment, while reading the Lotus Sutra, the sutra that he had disregarded as a young student. He wrote of this
experience, saying "suddenly I penetrated to the perfect, true, ultimate meaning of the Lotus". This event marked a turning point in Hakuin's life. His total enlightenment achieved, he dedicated the rest of his life to helping others achieve kensho. He would spend the next forty years teaching at Shoin-ji, writing, and giving lectures. At first there were only a few monks there, but soon
word spread, and Zen students began to come from all over the country to study with Hakuin. Eventually, an entire community of monks had built up in Hara and the surrounding areas, and Hakuin's students numbered in the hundreds. He eventually would certify over eighty disciples as successors. Hakuin died in Hara, the same village in which he was born and which he had transformed into a center of Zen teaching, at the age of 83.
The most important and influential teaching of Hakuin was his emphasis on, and systemization of, koan practice. Hakuin deeply believed that the most effective way for a student to achieve insight was through extensive meditation on a koan. The psychological pressure and doubt that comes when one struggles with a koan is meant to create tension that leads to awakening. Hakuin called this the "great doubt", writing, "At
the bottom of great doubt lies great awakening. If you doubt fully, you will awaken fully". Only with incessant investigation of their koan will a student be able to become one with the koan, and attain enlightenment. Hakuin's systematization of koan practice brought about a major revolution in Zen teaching. In the system developed by Hakuin and his followers, students are assigned koans by their
teacher and then meditate on them. Once they have broken through, they must demonstrate their insight in private interview with the teacher. If the teacher feels the student has indeed attained a satisfactory insight into the koan, then another is assigned. Hakuin's main role in the development of this koan system was most likely the selection and creation of koans to be used. In this he didn't limit himself to the classic koan
collections inherited from China; he himself originated one of the best-known koans, "You know the sound of two hands clapping; tell me, what is the sound of one hand?". Hakuin preferred this new koan to the most commonly assigned first koan from he Chinese tradition, the Mu koan. He believed his "Sound of One Hand" to be more effective in generating the great doubt, and remarked that "its superiority to the former
methods is like the difference between cloud and mud". One of Hakuin's major concerns was the danger of what he called "Do-nothing Zen" teachers, who upon reaching some small experience of enlightenment devoted the rest of their life to, as he puts it, "passing day after day in a state of seated sleep". Quietist practices seeking simply to empty the mind, or teachers who taught that a tranquil "emptiness"
was enlightenment, were Hakuin's constant targets. In this regard he was especially critical of followers of the maverick Zen master Bankei, and of certain trends within the Soto sect. He stressed a never-ending and severe training to deepen the insight of enlightenment and
forge one's ability to manifest it in all activities. He urged his students to never be satisfied with shallow attainments, and truly believed that enlightenment was possible for anyone if they exerted themselves and approached their practice with real energy.
Much of Hakuin's practice focused, as his teachings did, on zazen and koan practice. His motto was "meditation in the midst of activity is a thousand times superior to meditation in stillness". Hakuin's experiences of enlightenment seemed to come at unexpected moments, often when he was just walking or reading. One experience that he wrote about took place while he was walking through a torrential rain. As the
water reached his knees, he suddenly realized the meaning of a particular verse that he had read earlier, and was seized by enlightenment. He had many such experiences, both large and small. Laughter was a large part of Hakuin's reaction to his enlightenments, and he was known to burst into spontaneous laughter upon realizing the essence of a particular koan, causing those around him to believe him to be a madman.
Hakuin's early extreme exertions affected his health, and at one point in his young life he fell ill for almost two years, experiencing what would now probably be classified as a nervous breakdown by Western medicine. He called it Zen sickness, and sought the advice of a Taoist cave dwelling hermit named Hakuyu, who prescribed a visualisation and breathing practice which eventually
relieved his symptoms. From this point on, Hakuin put a great deal of importance on physical strength and health in his Zen practice, and studying Hakuin-style Zen required a great deal of stamina. Hakuin often spoke of strengthening the body by concentrating the spirit, and followed this advice himself. Well into his seventies, he claimed to have more physical strength than he had at age thirty, being able to sit in zazen
meditation or chant sutras for an entire day without fatigue. The practices Hakuin learned from Hakuyu are still passed down within the Rinzai school. Another important part of Hakuin's practice of Zen was his painting and calligraphy. He seriously took up painting only late in his life, at almost age sixty, but is recognized as one of the greatest Japanese Zen painters. His paintings were meant to capture
An extremely well-known and popular Zen master during his later life, Hakuin was a firm believer in bringing the wisdom of Zen to all people. Thanks to his upbringing as a commoner and his many travels around the country, he was able to relate to the rural population, and served as a sort of spiritual father to the people in the areas surrounding Shoin-ji. In fact, he turned down offers to serve in the great monasteries in Kyoto,
preferring to stay at Shoin-ji. Most of his instruction to the common people focused on living a morally virtuous life. Showing a surprising broad-mindedness, his ethical teachings drew on elements from Confucianism, ancient Japanese traditions, and traditional Buddhist teachings. He also never sought to stop the rural population from observing non-Zen traditions, despite
the seeming intolerance for other schools' practices in his writings. In addition to this, Hakuin was also a popular Zen lecturer, traveling all over the country, often to Kyoto, to teach and speak on Zen. He wrote frequently in the last fifteen years of his life, trying to record his lessons and experiences for posterity. Much of his writing was in the vernacular, and in popular forms of poetry that commoners would read.
