Four requisites aren’t the most important thing.
What is really necessary for living a life? The most people would say four requisites. Four requisites are the necessary element of human life, including food, clothing, medicine and habitat. If these four requisites , we are confident that it will live happily, but I think there are several requisites to make us happy as well.
The first requisite also is the food that we ensure that non-toxic, such as organic food, the food from the production from the farm, etc. The second requisite is the habitat, social, tradition, culture, beautiful contained in each region. The third requisite or clothing. In my view I have ever seen and touched. I think we are good parents. There are good sister or brother relatives and friends are great , If we were to give sincere to each other, like compassionate It is like the clothes to keep warm. Finally is the medicine. In addition to the warm clothing prevent disease pain. When that happens to be ill and then need to have treatment. In addition to medication, Dharma is also what is used to treat the body and mind.
So, these four requisites will keep human beings living in the middle way. But it is not sufficient just to live using the four requisites. People need to understand them and to put them into practice, which means living with understanding; which is what is meant by living in the middle way. That people need the four requisites is irrefutable as we all have to eat to stay alive; wear clothes to keep warm, or be civilized; live in accommodation to protect ourselves from the dangers of both animals and the weather and we all need to take care of ourselves both physically and mentally.
