on having no thought of killing, and not eating meat.

”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. 6:20

”Even though one may have some wisdom and the 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. 6:21

”These ghosts and spirits have their groups of disciples. Each says of himself that he has accomplished the Unsurpassed Way. 6:22

”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. 6:22

”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? 6:23

”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? 6:24
