In accordance with the worldly point of view, in many places individuals who eat meat are considered to be of a lower class; they have an unclear intellect, an unpleasant complexion, an unpleasant disposition, a foul smell, greater anger, etc. They are said to possess many faults.
Elaborating on the above statements, according to Tibetan mythology, two classes of beings have developed from the union of the father, the monkey and the mother, the ogress. One race craves meat, kills, is without compassion and harms others. In order to nourish their own bodies they take the lives of others and so forth. This harmful, coarse behavior is that of the line coming from the mother, the ogress and is classified as negative and impure.
The opposite of that is those who have abandoned taking life, do not eat meat, and being endowed with compassion, they do not harm. Analogous to one’s own body, they realize that the pain and suffering of others is the same as their own. They are the refined class, those of noble conduct belonging to the family of the bodhisattva-father, the monkey. They are classified as excellent and pure. This is clearly stated in the Mani Kabum, The Clear Mirror of History and other works.
Furthermore, among all peoples of all places, those who eat meat come to be known as an inferior class. Particularly, in India and some other countries, meat eaters, butchers, hunters, fishermen, and thieves are considered the lowest class of people by those who do not eat meat. Those who are of a higher class, such as the brahmins of India, look down upon and consider impure those who do eat meat and even shun them like people who have been struck by a seriously contagious disease.
In general, after eating meat, one’s body feels heavy and the consciousness is foggy and unclear. Also, these days in schools where the students do not eat meat the pupils are more intelligent and sharper witted while the faculties of those who do eat meat are dulled, and they are more forgetful.
Further, those who eat meat have a poor, unattractive complexion. It is said in the writings of the Kangyur and Tengyur that to non-humans and animals, the appearance of those who eat meat is ugly and unattractive like that of a demon. Those who eat meat think nothing of harming and injuring others and have lesser tendency to think of others’ benefit. To gods, nagas and other humans who abstain from eating meat, meat eaters have a very bad smell and their minds do not seem to have much happiness. Even others see that they are mentally agitated and appear unsettled. These are some of the results of eating meat.
