Heaven... nowadays, people aren't all that good. Things have gotten bad. That's why the acceptance rate to get into heaven is only ten (てん) percent!
Imagine yourself in line to get into heaven. You're super worried, because you're not sure if you'll get in. You heard there was a one in ten chance... those aren't good odds. Feel nervous in your imagination. Feel worried. Feel the pressure as you get closer and closer to the gate... will you make it?? Ten percent!
