How to reach HEAVEN (not a religious article)

A man with a dog walked along a long, wild, tiresome road. He walked, walked, tired, the dog tired too. Suddenly in front of him is a palace!

Beautiful gate, behind the fence - music, flowers, the murmur of a stream.
What is it? The traveler asked the gatekeeper.
This is paradise, you have already died, and now you can enter and relax for real.
“Is there water there?”
As many as you want: clean fountains, cool pools ...
And food?
Whatever you want.
“But the dog is with me.”
“Sorry, sir, you can’t go with dogs. You should leave the dog here. ”
And the traveler walked away.
After some time, the road led him to the farm. The gatekeeper also sat at the gate.
“I’m thirsty,” the traveler asked.
Come in, there is a well in the yard.
And my dog?
Near the well, you will see a drinking bowl.
What to eat?
“I can treat you to dinner.”
What about the dog?
There is a bone.
“What is this place?”
It is a paradise.
How is it possible? The doorkeeper at a palace nearby told me that heaven is there.
He’s lying. That is hell.
“How can I believe you?”
“Only those who do not abandon their friends can reach heaven.” gatekeeper replied.
