it's in us

i have come to think that heaven is neither a place nor an idea. it's a known fact just as Armagedon, Nirvana, and the United Kingdom are. Think of it this way.
How can someone go to a place their brain hasn't had access to before (in a sense of an idea) like heaven, if you never knew about heaven, how would you know it existed and if you didnt know it existed how would your soul be able to reach heaven if your brain has never experienced the knowledge... it's all too confusing and this picture has a bazillion words.
