Anybody know what is Nirvana and where we can find it? Learning Buddha dharma we need to dive in to the dharma world. Without knowing the truth about Dharma we can not reach our enlightenment.
It's  hard to know what Nibbana is without experiencing  it. The same as it  can't be known what an orange tastes like until it's taste is experienced, it can only be described with words. It's easier to say what it's not.

Nibbana is not nothingness or annihilation. Nibbana is the highest goal, better than the bliss of Heaven.

Nibbana is a state of great renunciation. There is Heaven within Samsara but it's imperminent and Nibbana is the   final permanent liberation beyond Heaven and outside of Samsara.

Nibbana is an end of the cravings which cause all the suffering of birth, old age, disease, death, lamentation and fear. 

Nirvana is the cure for our suffering here in the material world of Samsara caused by craving sensual pleasure and seeing reality as we want to see it rather than how it really is.

It's the correct understandung, virtue, peace and clarity of reality as it really is that leads to Nibbana.
