About the hell route
You watch bad memories in front of you. You look back at good memories. There are a total of 15 stages from 0 to 14. There are first half and last half in a stage.The first half of the stage is dark gray and the last half of it is pitch black. You go around your chest. After passing through this, you will enter the white area. From there you go up a lot, you will enter Nirvana.

Nirvana (heaven)
You finish around the six realms of samsara. If you go up directly above from there, you will enter Nirvana. Then you are liberated in Buddhism and awaken.
In nirvana you see your Buddha (your guardian spirit) a few meters in front of you. You see around it. The Buddha is almost in a gorgeous building. Other spirits are there. It moves.
This is the ultimate Buddhist meditation. Those who watches nirvana know the essence of Buddhism.

What is reincarnation? 
You first see scary people, hunger, and penance. You see poor people, criminals, and so on. This is the hell of Buddhism. The scenery changes from here. Cloudy gas comes out there. You see deserts, cliffs, floods. You climb a steep mountain.

And you enter the river. The plant will appear. You go into the woods. You then see the animals such as spiders, scorpions, wolves, ferocious dogs and mosquitoes. There is also a way to get out of reincarnation and go to heaven. This may have been interpreted as a rebirth in ancient times.

Where is the Great Enma (Yama)?
There is a Buddha at each stage. You can see the Buddhas in stages 0-14. They are called the Ten Kings in Japan and China. They are called the Ten Kings (Nara natinal museum). The most famous of these is the Great Enma (Yama wiki).
 You can see the Buddhas from the right side of the image of hell. This Buddha is hard to see.

Guided meditation
 Think it. "By the power made in Japan, let me experience these. Please. " When you think so, you can experience these by the invisible machine. Let's meditate.

1, Meditate. Think, "Please let me be selfless." It looks black.
2, "Take me in the six realms of samsara, please." You turn bottom right and enter it.
