Further, Ananda, if living beings in the six paths of any mundane world had no thoughts of killing, they would not have to follow a continual succession of births and deaths
Your basic purpose in cultivating Samadhi is to transcend the wearisome defilements. But if you do not renounce your thoughts of killing, you will not be able to get out of the dust.
Even though one may have some wisdom and manifestation of Chan Samadhi, one is certain to enter the path of spirits if one does not cease killing. At best, a person will become a mighty ghost; on the average, one will become a flying yaksha, a ghost leader, or the like; at the lowest level, one will become an earth-bound rakshasa.
The ghosts and spirits have their troops of disciples. Each says of himself that he has accomplished the unsurpassed way.
After my extinction , in the Dharma-ending Age, these hordes of ghosts and spirits will abound, spreading like wildfire as they argue that eating meat will bring one to the bodhi way.
Ananda I permit the bhikshus to eat five kinds of pure meat. This meat is actually a transformation brought into being by my spiritual powers. It basically has no life-force. You brahmans live in a climate so hot and humid, and on such sandy and rocky land, that vegetables will not grow; therefore, I have had to assist you with spiritual powers and compassion. Because of the magnitude of this kindness and compassion, what you eat that tastes like meat is merely said to be meat; in fact, however, it is not. After my extinction, how can those who eat the flesh of living beings be called the disciples of Shakya?
You should know that these people who eat meat may gain some awareness and may seem to be in Samadhi, but they are all great rakshasas. When their retribution ends, they are bound to sink into the bitter sea of birth and death. They are not disciples of the Buddha. Such people as these kill and eat one another in a never-ending cycle. How can such people transcend the triple realm?
When you teach people in the world to cultivate Samadhi, they must also cut off killing. This is the second clear and unalterable instruction on purity given by the Thus Come Ones and the Buddhas of the past, World Honored Ones.
Therefore, Ananda, if cultivators of Chan Samadhi do not cut off killing, they are like one who stop up his ears and calls out in a loud voice, expecting no one to hear him. It is to wish to hide what is completely evident.
Bodhisattvas and bhikshus who practice purity will not even step on grass in the pathway; even less will they pull it up with their hand. How can one with great compassion pick up the flesh and blood of living beings and proceed to eat his fill?
Bhikshus who do not wear silk, leather boots, furs, or down from this country, or consume milk, cream, or butter can truly transcend the world. When they have paid back their past debts, they will not have to re-enter the triple realm.
Why? It is because when one wears something taken from a living creature, one creates conditions with it, just as when people eat the hundred grains, their feet cannot leave the earth. Both physically and mentally one must avoid the bodies and the by-product of living beings, by neither wearing them nor eating them. I say that such people have true liberation.
What I have said here is the Buddha’s teaching. Any explanation counter to it is the teaching of Papiyan.
