The Platform Sutra of the Sixth Patriarch 六祖坛经
The Sixth Patriarch’s Dharma Jewel Platform Sutra; or simply the Platform Sutra of the Sixth Chan Patriarch Master Huineng (638-713); is an important sutra which examines the essence of the Mind and the Buddha-nature, or the Self-nature (自性). Self-nature is also non-self (anatman), and it is also Buddha-nature.
In Mahayana sutras, the Buddha also used the term Self-nature to speak about the Buddha-nature. This does not contradict the notion of non-self, provided that if one understands what each term means. One can also read the Mahayana Mahaparinirvana Sutra to understand this point.
Master Huineng famously described the qualities of the Self-nature (Buddha-nature):
What is the Self-nature (Buddha-nature)? It is originally pure in itself.
What is the Self-nature? It is neither created nor destroyed.
What is the Self-nature? It is originally complete in itself.
What is the Self-nature? It is originally unmoved.
What is the Self-nature? It can give rise to all dharmas.
(“all dharmas” means all physical and mental phenomena; everything in existence.)
何期自性? 本自清净。
何期自性?本不生灭。
何期自性?本自具足。
何期自性?本无动摇。
何期自性?能生万法。
This is a significant sutra in Chan Buddhism. Remember: the Buddha Dharma is One, and so all sutras can also be used to explain the Pure Land Dharma. Namo Amituofo.
