You still have a lot of time left to know about heaven! There is no use in knowing about heaven now otherwise there will not be any excitement left when you actually get there!
But it is important to understand enlightenment now. When you feel content you are enlightened. When everything feels like a dream you are enlightened. Just tell me, whatever has happened so far in your life, does it not seem more like a dream? You went to school, then college, got married, so many events took place in your life, all that is like a dream now. Isn’t it? Now you are sitting here among so many people, does this not seem like a dream? After today, many days and many years are going to come and pass and eventually we are all going to die, then will it not seem like a dream?
If you look into the past or the future or if you decide to wake up to the present everything will still feel like a dream, you will realise you are separate from the events you see and experience. This is enlightenment/ liberation. And when you feel free you feel happiness and where there is happiness that place in nothing short of heaven.
Doesn’t this place feel like heaven! We are not those who go to heaven but those who create heaven where we are! We bring heaven to us!
