nirvana is a realization of the world. when some one realize the true he will have not desire for every material and non material things in the world. another words it can call "Viragaya" he will have not any suffer from any thing. he can be strong in mentally. I think that is the Nirvana...
what's else....
I would like to read some pali, and learn some.
I would like to see the abidhamma.
i would like to be where the buddha first gave his sermon.
as i read and continue, i was worst than his most begineer student.
I like reading the inverted mind, and the voidness in the surangama sutra. i so enjoy reading the time when people first tasted the delicious things and become bodies.
