Suppose that in a forested wilderness there was an expanse of low-lying marshes, and a large herd of deer lived nearby. Then along comes a person who wants to harm, injure, and threaten them. They close off the safe, secure path that leads to happiness, and open the wrong path. There they plant domesticated male and female deer as decoys so that, in due course, that herd of deer would fall to ruin and disaster. Then along comes a person who wants to help keep the herd of deer safe. They open up the safe, secure path that leads to happiness, and close off the wrong path. They get rid of the decoys so that, in due course, that herd of deer would grow, increase, and mature.

I’ve made up this simile to make a point. And this is what it means. ‘An expanse of low-lying marshes’ is a term for sensual pleasures. ‘A large herd of deer’ is a term for sentient beings. ‘A person who wants to harm, injure, and threaten them’ is a term for Māra the Wicked. ‘The wrong path’ is a term for the wrong eightfold path, that is, wrong view, wrong purpose, wrong speech, wrong action, wrong livelihood, wrong effort, wrong mindfulness, and wrong immersion. ‘A domesticated male deer’ is a term for greed and relishing. ‘A domesticated female deer’ is a term for ignorance. ‘A person who wants to help keep the herd of deer safe’ is a term for the Realized One, the perfected one, the fully awakened Buddha. ‘The safe, secure path that leads to happiness’ is a term for the noble eightfold path, that is: right view, right purpose, right speech, right action, right livelihood, right effort, right mindfulness, and right immersion.
