In The Heart of the Buddha’s Teaching, Thích Nhất Hạnh emphasizes the transformative potential of the Buddha’s teachings. By detailing how suffering of all kinds can be replaced with happiness, compassion, and ethical actions, the author presents Buddhist practices as forms of healing and self-development.
Thích teaches the reader about a mindfulness practice in which practitioners identify and intentionally replace negative thoughts with wholesome ones. He explains, “The Buddha […] said […] to replace an unwholesome thought with a wholesome one by ‘changing the peg,’ just as a carpenter replaces a rotten peg by hammering in a new one” (61). Whether these “troublesome” thoughts are difficult habits or negative emotions, Thích believes that becoming aware of them and replacing them will foster “seeds of joy, peace, and liberation, heal and transform your suffering, and be truly present for many others” (62).
Another important practice is inclusiveness, in which practitioners manifest compassion and understanding to become more resilient in the face of hurtful actions. Thích argues that by becoming big-hearted and more understanding, people can absorb painful blows without becoming entrenched in cycles of negativity and violence. Thích explains this practice, writing, “If your heart is small, one unjust word or act will make you suffer. But if your heart is large, if you have understanding and compassion, that word or deed will not have the power to make you suffer. You will be able to […] transform it in an instant” (197-198). Thích lived this practice when he showed compassion towards American soldiers for their actions in Vietnam, knowing that they, too, were victims of manipulation and violence. This spirit of forgiveness allowed him to become a credible advocate for peace instead of becoming overwhelmed with hateful intentions.
The author emphasizes how transforming one’s own suffering into happiness is connected to ethical actions, which benefit others as well. For instance, by following the First Mindfulness Training, people live out their respect for plants, animals, and people, preventing exploitation and embracing compassion instead. Thích provides the concrete example of avoiding foods which are made by exploiting animals and people. In doing so, people will reduce their own physical ailments, and contribute to bettering their own family and society as well. He explains, “When we smoke, drink, or consume toxins, we are eating our own lungs, liver, and heart. If we have children and do these things, we are eating our children’s flesh. Our children need us to be healthy and strong” (31-32).
By connecting people’s individual actions with the health of their families and community, the author shows how transforming suffering can begin with a single person and have wide-ranging positive effects.
Thích repeatedly calls for the reader to integrate the Buddha’s teachings into their everyday life. In doing so, he presents Buddhism as a relevant and vital guide to life, steering the reader away from a focus on intellectual understanding and towards a lived practice. He underscores the importance of people’s actions in creating their reality, writing, “if we practice the ignoble eightfold path, suffering will naturally be the outcome. The practice is to face our suffering and transform it in order to bring about well-being. We need to study the Noble Eightfold Path and learn ways to put it into practice in our daily lives” (46).
Thích believes that this suffering is a useful foundation for understanding— and applying—Buddhist principles, and that this lived experience is more valuable than book knowledge. For instance, he points to his experience of surviving war in Vietnam and managing to overcome feelings of hatred towards American soldiers to continue his good work living the Buddha’s message. He writes, “This is the kind of suffering many of us have overcome, and the teaching is born out of that suffering, not from academic studies” (204). Indeed, Thích is highly conscious of how it is easy to merely read about the Buddha and comprehend his words or beliefs. He urges the reader to not stop at this comprehension, but to always channel their understanding into their actions. When explicating the Four Noble Truths, he coaches the reader to understand these teachings “not just intellectually but experientially” (28, emphasis added).
For instance, he asks parents to apply their learning about different “nutriments” by protecting their children from negative sensory experiences, like violent media. He explains, “When we watch TV, the program is our food. Children who spend five hours a day watching television are ingesting images that water the negative seeds of craving, fear, anger, and violence in them” (32). This concrete example encourages the reader to recognize how they should apply Buddhist practices in their everyday decision-making.
The author invites the reader to incorporate Buddha’s practices into daily life by insisting that words and pictures will only get them so far. Thích calls this superficial understanding “Image teaching,” which only touches the surface of reality and may burden people with more concepts and perceptions (55). He concludes, “conceptual knowledge is never enough. The seeds of Right View, the seed of Buddhahood, are in us, but they are obscured by so many layers of ignorance, sorrow, and disappointment. We have to put our views into practice” (56).
Another key theme in Thích’s work is liberation through mindfulness. The author argues that this famous Buddhist practice is the key to liberating oneself from all kinds of negative feelings and traits, such as wrong view, false perceptions, and existential suffering. Thích’s explanations show how practitioners can incorporate mindfulness into any area of their life.
According to Thích, mindfulness is so effective because it helps to suppress negative instincts and emotions while nurturing positive ones. He points to how the human mind seems to be inherently wired to revisit painful experiences and negative emotions, writing, “If we sit there and allow the negative thinking connected to past experiences to come up, we are eating the toxic matter of consciousness. Many of us sit and think, and the more we think, the more angry, upset, and in despair we become” (36). The author laments how this rumination is detrimental to the individual and those around them. He compares these entrenched cycles of painful thoughts to being stabbed, writing, “Every time we ruminate on the past, it is like stabbing ourselves with a sharp knife. We suffer, and our suffering spills out to those around us” (37).
Thích points to mindfulness as the remedy for this mental anguish. He argues that focusing on the present is a valuable tool for pulling people out of their repeated cycles of thinking. By using mindfulness to concentrate deeply on the good in the present moment, people can ease their suffering and become free to enjoy their current reality instead of reliving their past. By offering specific meditative practices, the author invites the reader to try mindfulness in its different forms.
For instance, he suggests a sitting meditation, in which the practitioner thinks deeply to identify the causes of their suffering and writes them down. Thích coaches the reader to consider how they have been feeding their suffering through different poor nutriments, and how they will change their behaviors. Thích explains that this form of mindfulness is a way of showing self-compassion, as people must “embrace your suffering like a mother holding her baby” (38). With regular practice of such techniques, Thích argues that people will free themselves from their burdens.
Thích thus extols the benefits of these practices, writing, “After three months or six months of mindful sitting, mindful walking, and mindful looking, a deep vision of reality arises in us, and the capacity of being there, enjoying life in the present moment, liberates us from all impulses and brings us real happiness” (34).
