Summary
This talk is a closing Dharma discourse delivered at the Still Water Meditation Hall in the Upper Hamlet on June 21, 2012, the final day of a 21-day retreat. The speaker opens with practical announcements about the day’s walking meditation, the return bus schedule, visits to Thich Nhat Hanh’s hut, upcoming lazy days, an ordination ceremony for novices on July 4, and the summer opening of Plum Village on July 6. He also explains that the monastic community will later move to the European Institute of Applied Buddhism to offer retreats for Dutch-speaking and German-speaking participants, and he gives instructions for retreat certificates signed by Sister Tung Nghiem. The central teaching of the talk is that the retreat has been a challenge not in the sense of Buddhism versus science, but as a shared invitation for practitioners to challenge themselves. The speaker emphasizes that both meditation practitioners and scientists must continually improve their teaching, learning, and practice. The goal is to generate more mindfulness, concentration, and insight so that practice can transform suffering, nourish life, and deepen understanding of ultimate reality. He presents the Buddha as someone who also refined his teaching and built a community after enlightenment, underscoring that the Sangha is essential: without a Sangha, a Buddha cannot do much. The Sangha is described as the Buddha’s masterpiece, and each person is encouraged to see oneself as a cell in the Buddha body and Sangha body, contributing energy that nourishes the whole. A major theme is the interdependence of understanding and compassion. The speaker revisits the Four Noble Truths, explaining that Buddhist practice begins by recognizing suffering, looking deeply into its causes, and allowing understanding to arise. From understanding, compassion naturally arises; without understanding, love cannot fully flower. He stresses that suffering and happiness inter-are, like mud and lotus, and that practitioners can transform suffering into happiness rather than fleeing from it. This is tied to the broader Buddhist insight that reality is organic and relational, not fixed or isolated. The discourse then moves into a detailed exploration of non-discrimination and nonduality. The speaker discusses pairs of opposites such as birth and death, being and non-being, coming and going, and sameness and otherness. He argues that the ultimate transcends these conceptual pairs and that direct experience, rather than abstract thinking, is necessary to touch it. He draws on Zen and Soto Zen ideas of non-thinking and non-measuring, and he uses the example of tasting a mango to show that direct experience cannot be fully captured by language. He also introduces the Buddhist notion of skillful adaptation, or wisdom in the use of concepts, explaining that language can be used provisionally to guide people beyond language itself. To make these ideas concrete, he offers vivid examples from the body and from daily life. The right hand and left hand are used to illustrate non-discrimination, mutual care, and the absence of superiority or inferiority. He also describes a poem written with both hands, and a moment when one hand injures the other and immediately tends to it as if caring for itself. In true love, he says, the distinction between lover and beloved disappears. The same principle applies to the relationship between afflictions and enlightenment: enlightenment is not outside suffering, and suffering is not outside enlightenment. He extends this to the formula that all things are made of non-thing elements, such as a flower being made of non-flower elements. The talk also engages science, especially quantum physics and Einstein’s relativity, as examples that challenge simplistic notions of separateness, fixed identity, and independent existence. The speaker suggests that scientists, like Buddhist practitioners, must learn to release rigid concepts in order to approach unity and interbeing. He explains conditioned genesis, dependent arising, and emptiness as the framework through which phenomena are understood to arise through mutual dependence. The cloud metaphor becomes a major teaching device: a cloud continues as rain, tea, corn, and many other forms, so birth and death are only apparent when seen superficially. The river story further illustrates aimlessness, one of the three doors of liberation. A river that has been chasing clouds eventually realizes that it is already made of clouds and water, and thus no longer needs to pursue anything outside itself. This realization brings freedom, peace, and enlightenment. In the closing section, the speaker returns to the Sangha as the living expression of the Buddha body and the hope for the world. He reminds listeners that the five mindfulness trainings and the fourteen mindfulness trainings embody the wisdom of interbeing and non-discrimination, and he encourages everyone to continue building Sanghas in their families, neighborhoods, and societies. The talk ends with gratitude, an invitation to visit Thich Nhat Hanh’s hut and gather for walking meditation, and a chant affirming mutual presence: no coming, no going; I am in you and you are in me.
