What to read after Hyakujo: The Everest of Zen, with Basho’s Haikus?

Hyakujo was the direct heir of Ma Tzu and became most well known for his establishment of the first truly Zen monasteries and his treatise on sudden enlightenment. To understand Hyakujo, the first thing is to understand that enlightenment can only be sudden. The preparation can be gradual, but the illumination is going to be sudden. You can prepare the ground for the seeds, but the sprouts will come suddenly one day in the morning; they don’t come gradually. Existence believes in suddenness. Nothing is gradual here, although everything appears to be gradual; that is our illusion.
