Nirvana and Buddhist Liberation

My Buddhist group had a meeting last night. It was a discussion of Nirvana. That was a bold attempt in itself. In the Buddhist tradition, there is a common understanding that Nirvana is not something we can talk about. Yet, the realization of Nirvana is also the ultimate goal of Buddhist practice. I, therefore, proposed the topic and hoped that our group could explore the idea of Nirvana together.
