One thing does worry me though. Some practitioners from China who used to be vegetarian went to Tibet to study Vajrayana. Instead of learning the essence of Tibetan Buddhism, they adopted the bad habit of consuming meat, even to the point of being excessive sometimes. They believe this is the way of real Vajrayana, and that as a yogi of Vajrayana, eating meat is only right and natural. There are some Chinese monastics who claim to be Vajrayana practitioners after returning to China from Tibet. Clad in the monastic robes, they buy lots of meat and alcohol for the ganachakra. After reading the relevant text for the occasion, they start to feast on the food and the alcohol. This is their idea of a ganachakra. Many ill-informed lay Buddhists also think that alcohol is nectar of the gods, and that eating meat is not a problem. They even look down on those of the exoteric schools who still remain vegetarian. All of these views and attitudes are wrong and must be corrected.
