He’s another supreme deity driven further up the Heavenly Ladder due to pesky human behavior.
This time the culprit was an old woman pounding yams with a long pole. (Haven’t we heard this before somewhere?) The pole flew up out of control towards the holy anatomy. Thud!
Ouch! NYANKOPON wasn’t going to suffer indignities like that. So he ascended to Heaven in a huff.
The humans were terribly upset and tried to build a ladder to Heaven to find him. This was quite dangerous as the ladder was made of yam poles and quite rickety. But they persevered until they were just one yam pole short. "Take one from the bottom", NYANKOPON advised. They did of course. Crash!
When they hit the ground they became quite dead. Very peaceful and quiet. Silence. Bliss. NYANKOPON found them quite tolerable in this state. That’s why only the dead can get to Heaven — they’re much quieter and don’t disturb the peace.
