Final answer:
Zen Buddhists aim to practice Zazen, a meditation technique leading to enlightenment. Nirvana is the ultimate state of peace that arises from the extinction of all desire, which Zen Buddhists might achieve through dedicated practice and guidance. The Noble Eightfold Path is followed to reach nirvana.
Step-by-step explanation:
The term used by Zen Buddhists for the aim of their practice is Zazen (D), which is the sitting meditation practice at the heart of Zen Buddhist training. While closely related to the concept of nirvana (B), which is the state of ultimate peace found in the extinction of all desire, Zazen is specifically the meditative discipline that may lead to such a state.
Zen Buddhists use meditation and the guidance of a master to understand that the world is illusory, leading to enlightenment and liberation from the cycle of samsara.
The word "Buddha" means "The Awakened One" (D) and refers to an individual who has attained enlightenment. The term nirvana represents the goal of the Buddhist path, in which one achieves a state of being where desire does not rule one's existence (D). This state is achieved by following the Noble Eightfold Path, which leads to discernment, enlightenment, and ultimately, nirvana.
