"Nirvana can be realized in this very life; it is not necessary to wait till you die to 'attain' it." (引自小乘佛教高僧Walpola Rahula的經典名著What the Buddha Taught, P43)
"what is compared to a flame or a fire gone out is not Nirvana, but the 'being' composed of the Five Aggregates who realized Nirvana....Nirvana is never compared to a fire or a lamp gone out."
