Shundo David Haye – Zen Priest

‘Only buddhas and ancestors know the opening and falling of flowers in the sky [sky blossoms] and earth blossoms, and the opening and falling of world blossoms. They alone know that flowers in the sky, earth blossoms, and world blossoms are sutras. This is a standard of studying buddhas.
Because what buddha ancestors ride on are flowers in the sky, the buddha world and all buddha dharmas are flowers in the sky. But mediocre and foolish people think that the obscured eyes in the Tathagata’s statement “What is seen by obscured eyes are flowers in the sky” means the confused eyes of sentient beings. Because their sick eyes are already confused, they think that flowers in the sky are seen in pure space. Being attached to this view, they mistakenly see that none of the three realms and the six paths, existent buddhas and nonexistent buddhas, exist. If such deluded seeing stops, they may stop seeing such flowers in the sky and think the Tathagata said that in original emptiness there are no flowers. 

What a pity! They do not know from beginning to end the moment of flowers in the sky spoken by the Tathagata. The meanings of “obscured eyes” and “flowers in the sky” have not been grasped by ordinary people and those outside the way. 

Buddha tathagatas practice these flowers in the sky and attain the robe, the way of sitting, and entering the room. They attain the way and the fruit of buddhahood. 

Taking up a flower and blinking are both the fundamental point actualized by obscured eyes and flowers in the sky. That the treasury of the true dharma eye, the wondrous heart of nirvana, has been authentically transmitted without cutting off is called obscured eyes and flowers in the sky. Enlightenment, nirvana, dharma body, self nature, and so on are two or three petals of the five petals of flowers unfolding in the sky.’ (Shobogenzo Kuge)
