Although Vajrayana requires its practitioners to accept five meats and five nectars as part of the practice, beginners must stay away from them and use instead visualization or some herbal medicine as substitutes. If not, plainly eating meat and drinking alcohol will create huge demonic obstacles to one’s practice. What does it mean by demonic obstacle? On hearing this term, many people instantly picture a human or non-human being with eyes, ears, multiple heads and hands. These actually are just petty demons. The king of demons that would obstruct our practice is none other than the habit of eating meat. Such is the view of Vajrayana. So who says that eating meat is permissible with Vajrayana?
