Which of the following is NOT one of the Four Noble Truths?

The reason why the choice indicating that "the cycle of life is eternal" is not one of the Four Noble Truths is that it does not align with the fundamental teachings of Buddhism regarding the nature of life and suffering. The Four Noble Truths are foundational to Buddhist philosophy and address the existence of suffering, its cause, the possibility of cessation, and the path to achieving that cessation.

The first truth, Dukkha, acknowledges that suffering is an inherent part of existence. The second truth, Tanha, identifies desire and attachment as primary causes of suffering. The third truth, Niroda, reassures that it is indeed possible to end suffering by overcoming desire.

In contrast, the concept of the cycle of life being eternal is not part of the Four Noble Truths; rather, it is often associated with the understanding of samsara, the cycle of birth, death, and rebirth. However, samsara is viewed from a perspective that emphasizes its temporary nature, as liberation from this cycle is ultimately the goal of Buddhist practice. Thus, the correct answer highlights a misunderstanding of the essential teachings of Buddhism regarding suffering and its cessation.
