Monks in Thailand seek alms every morning. As the monks cannot choose the food they like and reject any food offered by the devotees. Hinayana Buddhism is not Vegetarianism; therefore devotees may consume meats from slaughtered
including pork, chicken, beef, mutton & etc.
If the relevant monk does not like the foods from the devotees, they have to offer it to the others. There are many monks in Thailand that consume meat, unlike the Chinese Taoists and Buddhists in Southeast Asia who decline to accept.
Long time ago, in India where the bodhisattva Guan Yin lives, the life of the peoples is very poor. The depends on the cow for their living, and the cow have to support the whole family, they served as public transports or carriage “often have ropes tied through their nose so that they can be dragged off the trucks”.
They typically go without food and water, or taking rest for the duration of the journey. These are what they called the Holy animal, which also has to offer milk to
all kids over the years. The lifespan of a cow is about 20 years.
They have to do their job everyday for as long as the lives; this is what they valued the appreciation of the Charitable Contributions of the Sacred Cow in returned. This had caused many Buddhist devotees to refrain from taking beef.
