Perfect happiness is called

Perfect happiness is often referred to as "eudaimonia," a term derived from ancient Greek philosophy, particularly associated with Aristotle. It signifies a state of flourishing or living in accordance with virtue and purpose. In contemporary discussions, it can also be described as "nirvana" in Buddhist contexts, representing a transcendent state free from suffering and desire. Ultimately, the concept varies across cultures and philosophies, but it generally embodies an ideal of complete fulfillment and well-being.
