What or where is Nirvana? Is there any proof that such a dimension exists?
Nirvana is a supra-mundane state realized by Buddhas and Arahats, a state of liberation through full enlightenment. It is not something to be described in mundane terms or understood by mundane knowledge, but is realized only by intuitive wisdom. Nirvana also means the destruction of lust, hatred, and ignorance, erasing egoism and discovering deliverance from suffering. The Buddha described the state in terms such as infinite, supreme bliss, and peace. Nirvana is not a kind of heaven where the ego resides; it is a spiritual place that is spaceless and timeless. This is the “abode of immortality” which is not spatially located. However much we may speculate, we shall never be in a position to comprehend its real nature. The best way to understand Nirvana is by self-realization.
