Nirvana - Wiki
Nirvana is the Sanskrit equivalent of Nibbana, which is the Pali word for it.
Nirvana is used two ways:
- To refer to the complete discontinuity of the field of experience called Fruition.
- To refer to the waking experience of the arahat.
These are radically different usages, making Nirvana another ambiguous term that must be interpreted by its context.
