How can I get more information about the journey to heaven?

I ride my ramshackle bicycle that has no seat to rest my skinny buttocks well.
This thorny road is not easy to go and I scared that anytime I get a tyre puncture or cut.
Along the road I found cemeteries and these dumb tombs never talk.
You could see only their dates of birth and burial and what else?

To a faraway friend only in dreams I have seen him
And he looks like me a sad face but a strong heart?
