The Diamond Sutra offers the Buddha's insights on dualism and illusion. He speaks of how to develop the insight, the "diamond," that can cut through any obstacle on the road to enlightenment.

This sutra presents a dialogue between the Buddha and his disciple Subhuti that illuminates how our minds construct limited categories of thought. Thich Nhat Hanh's commentary on the text shows how we must move beyond personal enlightenment to become fully enlightened beings who work to alleviate the suffering of others. Nhat Hanh writes about the daily applications of the sutra and how we can use its wisdom to encounter a deeper reality and act in the world skillfully and effectively.
