The hells' anxiety and suffering
Is devoid of doors, yet one bores right in.
Giving rise to delusion, deeds are done.
The retribution is borne in due accord.

Commentary:
The hells are a miserable place. Anyone who would like to take a vacation in the hells can do so any time at all. I can guarantee that you'll get there right away. How?

It is said,

Depressed and melancholy, you roam through the hells.
Happy and smiling, you enjoy eternal youth.
Weeping and woe make a small dark room in the hells.

Once you become worried, you travel to the hells to take a vacation. If you get worried, you plant a seed for the hells. If you smile, you plant a seed for the heavens. It is said,

From ancient times, the divine immortals have had no other practice
Than merely being happy and not being sad.

If you become depressed, you take a trip to the hells. If you smile all the time, you look youthful even if you are old. If you cry, you give yourself a lot of vexation.

In general, there is no happiness in the hells. They are full of suffering and distress. The hells' anxiety and suffering / Is devoid of doors, yet one bores right in. Unlike jails built to hold criminals, the hells haven't any doors. However, if you are due to go to hell, when you arrive it is just as if a door opened, because you find yourself worming and boring in where there was no entrance.

Giving rise to delusion, deeds are done. Why do you go to the hells? Ignorance and afflictions make you stupid and confused, so you create bad karma and don't do good deeds. The retribution is borne in due accord. When you create bad karma, you fall into the hells to undergo the retribution. There is no end to this cycle once it starts. You receive exact repayment for whatever karma you create, and the retribution is never off by even a hair's breadth.
