"Thousands of rivers reflect thousands of moons; miles of cloudless sky, miles of pristine clarity." and “Thousands of rivers all reflect the same moon.”

Self-nature or pure consciousness is like a projector casting all the shapes and forms and bringing forth everything. 

“self-nature” in Chan, the “Buddha-nature" in Buddhism, “Brahman” in Hinduism, and the “Dao” or Wuji (ultimate reality) in Taoism—all indicate the same pure essence.

Chan has nothing to do with religion. It broke all doctrine and threw away the talks about reincarnation and karma. It set all rules, beliefs, and doctrines on fire, reducing them to ashes. Chan only has a single query: Are you awake or not? It is about seeing one's true nature.
