The poem from the Shobogenzo chapter ‘Flowers in the Sky’ was written by Zhang Zhuo upon his enlightenment. It begins, “Radiant light serenely illuminates the sands of the Ganges.” Talking about the mind of awakening is very difficult. The poem ends: “Nirvana and birth-and-death are both flowers in the sky.”https://youtu.be/34xQxJYoR1k
