Diamond Sutra and Heart Sutra
The Diamond Sutra and Heart Sutra are pivotal texts in Mahāyāna Buddhism, emphasizing the perfection of wisdom and the concept of emptiness. The Diamond Sutra, dated to May 11, 868, is notable for being the earliest dated printed book and the first known work with a public domain dedication. The Heart Sutra, which addresses the fundamental emptiness of all phenomena, is a key scripture in various Buddhist traditions. Both texts have significantly influenced East Asian Buddhism, particularly within the Chan (Zen) tradition.
