Health preservation is the highest state of mankind. When a person is born, his fate is basically fixed. What he should do, what he should not do, what he should eat and what he should not eat. If he can follow his luck, he will be safe. An enlightened person will discover and know his luck, and know what he should and should not do. Therefore, keeping in good health is definitely not a simple imitation, and people follow suit. Don't envy others, find your own understanding from your own heart. So how can people find out if they let nature take its course? Actually, it's too simple. You are sick, you are uncomfortable, you are uncomfortable, then you are against nature. It is indispensable to conform to the nature of the outside world and the nature of one's own inner destiny.
