nirvana - NEAR-vah-nah - in Buddhism, the final goal, a transendent state in which a state of perfection is produced - resulting in a completely enjoyable experience.

Example: "Encouraging us not to delay pleasure, a Times science article says it can become a self-perpetuating process if one fixates on some imagined nirvana; the longer you wait to open that prize bottle of wine, for example, the more special the occasion has to be, and it may be delayed forever."
