Hakuin's Naikan Meditation

Hakuin's Ailment and Recovery

Hakuin Ekaku, a pivotal figure in Japanese Zen Buddhism, likely experienced the onset of his ailment during his late twenties. This condition, characterized by a complex interplay of physical and mental distress, persisted for several years, significantly impacting his life and practice before he successfully overcame it around the age of thirty-one. During this challenging period, Hakuin embarked on an extensive exploration of various healing modalities to alleviate his suffering and regain his health. This quest led him to delve into Chinese medical, Buddhist, and Taoist texts, where he sought insights into potential remedies and therapeutic techniques. It is plausible that he acquired knowledge of specific meditation techniques from these texts, which he then adapted and integrated into his own practice.

Guidance from Egoku Dōmyō, an Ōbaku teacher, proved instrumental in Hakuin's recovery journey. Dōmyō offered a seemingly paradoxical yet profound piece of advice: to focus on uninterrupted zazen (seated meditation). He emphasized that while excessive zazen could indeed contribute to the development of Zen sickness, it was also the ultimate key to its cure. This approach, which appears counterintuitive at first glance, underscores a fundamental tenet of Zen philosophy – the idea that the very source of suffering can also be the path to liberation. By confronting the potential causes of his ailment head-on through diligent and focused meditation, Hakuin was able to transform his suffering into an opportunity for profound self-discovery and healing.

Preface to Idle Talk on a Night Boat

In 1757, Ogawa, a discerning bookseller hailing from Kyoto, approached the monks associated with Hakuin, seeking access to a manuscript of considerable interest and potential value. This manuscript bore the intriguing title of Idle Talk on a Night Boat. The contents of this manuscript were believed to encompass a collection of secret and esoteric techniques purportedly designed to facilitate the cultivation of life essence, the disciplined control of $ki$ (vital energy), and the attainment of longevity. Essentially, the manuscript was rumored to provide detailed instructions and practices on how to enhance one's overall health, vitality, and lifespan. The very fact that a bookseller of Ogawa's stature would actively seek out such a manuscript underscores the prevailing interest in health and longevity practices during that historical period. Furthermore, it highlights the widely held perception of a tangible connection between dedicated Zen practice and the attainment of physical and mental well-being. The pursuit of such knowledge was not merely academic but deeply personal, reflecting a widespread desire to harness the power of Zen principles for practical health benefits. Historians note that the manuscript was also sought by members of the imperial court to extend their lives.

The bookseller, Ogawa, was persistent in his attempts to secure the manuscript and made multiple visits to the monastery, each time emphasizing the potential benefits the text could offer in promoting health and extending life. However, the monks remained hesitant, citing concerns about the manuscript's sensitive content and the potential for misinterpretation or misuse by those who were not adequately grounded in Zen principles. Despite Ogawa's repeated assurances of discretion and responsible handling, the monks ultimately declined to grant him access to the manuscript, and it is said to remain locked away inside the monastery to this day.
