What does the term 'enlightenment' signify in Buddhism?

In Buddhism, the term 'enlightenment' signifies the ultimate liberation from suffering, often referred to as "nirvana." This state represents the profound understanding of the nature of reality, where an individual transcends the cycle of birth, death, and rebirth (samsara). Enlightenment involves the realization of the Four Noble Truths, which describe the nature of suffering and its cessation through the Eightfold Path. Achieving enlightenment means that one has liberated themselves from desires and attachments, leading to a state of peace and freedom from suffering. This concept is central to Buddhist teachings and illustrates the goal of spiritual practice within the religion.
