reached total Nirvana, at the age of 80.
'Nirvana' is a Sanskrit word that means "extinguishing", when the candle flame of uncontrolled passions ceases to flicker.
Buddha described nirvana as the state of perfect peace that is free from craving, anger and other emotions that afflict the mind. The person is at peace with the world, has compassion for all and gives up all obsessions and fixations.
The root causes of all states that afflict the mind are dissolved by living a disciplined life and applying the eightfold path. Nirvana is believed to be the end of all want and suffering, and the end of the cycle of rebirth (thus no more re-incarnation) and is the ultimate aim of Buddhism.
Nirvana Day is celebrated in different ways. Some Buddhists meditate about their lives and how they can work towards gaining the perfect peace of Nirvana. In monasteries Nirvana Day is treated as a social occasion, where food is prepared and some people bring presents such as money, household goods or clothes. Other Buddhists will read passages from The Paranibbana Sutta, a highly revered Buddhist canonical text which describes the last days of Buddha, while others may reflect on those who have recently passed away.
