Book excerpt: The Diamond Sutra, a mainstay of the Mahayana tradition, has fascinated Buddhists for centuries because of its insights into dualism and illusion: the "diamond" can cut through any obstacle on the road to enlightenment. In the Diamond Sutra, the Buddha responds to a disciple's question about how to become a Buddha. The Diamond that Cuts Through Illusion presents a dialogue between the Buddha and his disciple, Subhuti, which illuminates how our minds construct limited categories of thought. The answer: we must move beyond personal enlightenment to follow the path of the Bodhisattvas, fully enlightened beings who postpone Nirvana in order to alleviate the suffering of others. It offers us alternative ways to look at the world in its wholeness so we can encounter a deeper reality; develop reverence for the environment and more harmonious communities, families, and relationships; and act in the world skillfully and effectively. This revised edition includes Thich Nhat Hanh’s translation of the Sutra from the Chinese and, in his commentaries, his own diamond sharp insight, including new work on the environmental implications of the Diamond Sutra. A beautiful edition of one of Buddhism's central texts.
