To measure out right feelings in due size

A  triolet can act as a device
That stops the flood of feeling  drowning  all
If it   embeds a phrase  for wiser eyes.
A  triolet can act  when well contrived
To measure out right feelings in  due size
Then we are  sheltered from  apocalyptic falls
A  triolet’s a  poem , a    rhymed device
To contain the flood of feelings which appalls.
