In his work, Walpola Rahula addresses the Buddhist concept of Dukkha, or suffering and impermanence in a human life cycle and explains how people’s thoughts and actions can continue this cycle of pain. In addressing this aspect of Buddhist belief, the author develops a theme of understanding and resolving suffering. One facet of this theme is the Buddhist belief that suffering is a consequence of evil thoughts or actions, called Karma, which then guarantees one’s rebirth and the continuance of Dukkha. Rahula’s detailed explanations of the Buddha’s Eightfold Path and its instructions on ethical conduct, mental discipline, and wisdom suggest that by following the Buddha’s teachings people can effectively minimize suffering for themselves and others in the present, and that these efforts bring them closer to realizing Nirvāṇa and avoiding rebirth in the future.

Rahula describes how the Buddha urged his followers to do everything possible to avoid causing others emotional or physical pain. For example, in the Noble Eightfold Path, he instructs followers to communicate “with words that are friendly and benevolent, pleasant and gentle, meaningful and useful,” and to “live by a profession which is honorable, blameless and innocent of harm to others” (82-83). The Buddha also forbade killing animals. Rahula explains that such rules are meant to eliminate suffering in people’s and animals’ lives by creating a “happy and harmonious life both for the individual and for society” (83). In emphasizing both interpersonal ethics and lifestyle choices, Rahula highlights how small, daily actions play a role in the broader spiritual aim of reducing suffering. These instructions reveal that the Buddha was concerned for people’s quality of life and believed that reducing physical and emotional pain was a noble act.

However, these beliefs on suffering apply to the bigger picture of existence and rebirth, too. Rahula claims that it is possible for anyone to extinguish Dukkha forever by realizing enlightenment and avoiding rebirth, but it depends on their actions in the present. Rahula posits that practicing the “moral conduct” of the eightfold path promotes people’s “spiritual development,” bolstering their ability to realize enlightenment (83). His explanation emphasizes people’s unique ability to resolve their own cycle of suffering through their own actions, since in Buddhist thought Dukkha can only be undone by itself. He emphasizes how people hold the key to their own future, explaining, “We must therefore clearly and carefully mark and remember that the cause, the germ, of the arising of dukkha is within dukkha itself, and not outside; and we must equally well remember that the cause, the germ, of the cessation of dukkha, of the destruction of dukkha, is also within dukkha itself, and not outside” (60). This view reframes suffering not as punishment or fate, but as an opportunity for transformation. This complex concept challenges the reader to consider how their own thoughts and actions could bring resolution to their suffering as well as others—and possibly stop its cycle for good.
