## The Right Time to Speak
**Commentary:** To illustrate this point, the text uses the term "Ural" as a broad metaphor for the "world," encompassing the activities, endeavors, and specific states of the community of noble beings. Noble-bodied beings, from their previous states, undergo a transformation from the stages of embryo, fetus, and womb, to the noble states of childhood, youth, and adulthood. This signifies that noble-bodied beings, like humans, experience different stages of life marked by time, such as childhood, youth, etc., which are clearly observable. However, it is not evident that they remain the same throughout their previous lives. Similarly, all stationary and mobile beings undergo various stages of existence, which should be understood. All beings are afflicted by physical and mental suffering, and they are seen to experience different states. Therefore, one should refrain from harming any being. Just as one should avoid causing harm, all beings experience suffering as unpleasant and happiness as pleasant. Therefore, one should not harm any being, including all beings. This verse highlights the impermanence of beings and emphasizes the importance of non-violence.
## The Essence of Knowledge
**Commentary:** Why should one not harm beings? The answer lies in the principle of happiness. This is the essence of knowledge for a wise and discerning individual: to not harm any living being, whether stationary or mobile, and to not cause them any distress. This principle also implies that a wise person would not lie, steal, engage in sexual misconduct, accumulate possessions, or eat after sunset. This is the essence of knowledge, which encompasses all actions.
