There is a difference between Nirvana in Buddhism and the happy feelings we feel in our lives.

@slowwalker, Exactly right. For take Nirvana to someone, he or she have to do more difficult tasks. They want to sacrifice lot of their passion. But if someone got Nirvana he/she never born in the world. Actually nirvana is a huge achievement in human's life Buddhists believe. But more people looking their secular world's happy. It's temporary. You have explain explain perfectly. Beautiful perspective of view this temple.
