Anecdotes
As a child, the young Hakuin was terrified by a sermon about the eight burning hells. This fear of damnation became the driving force of his spiritual quest and pushed him, around the age of fifteen, to enter the monastic life to escape this fate.
At 24, while meditating on the kōan “Mu” at Eigan-ji temple, Hakuin experienced his first great awakening: hearing the sound of a morning bell, he felt as though the entire universe was collapsing. Convinced he was finally liberated, he was sharply put back in his place by his master Shōju, who deemed his awakening incomplete.
A legend tells that he was unjustly accused of having gotten a village girl pregnant; the infant was handed over to him. Hakuin only replied “Ah, is that so?” and raised the child. When the truth came out, he gave the child back with the same serenity: “Ah, is that so?” — illustrating his detachment.
Worn out by excessive practice, Hakuin fell into a severe “Zen sickness” (nervous breakdown). He was cured thanks to a hermit named Hakuyū, who taught him a method of meditation through breathing and visualization, which he later described in his book Yasen Kanna.
Hakuin is famous for having formulated the most well-known kōan in the West: “What is the sound of one hand clapping?”. He invented it to offer beginners a more accessible gateway to awakening than the classic “Mu”.
