How long is the mantra of Buddhist scriptures effective?

The curse of getting rid of diseases in Buddhist scriptures will have the effect of one time, and it will have the effect of ten times when read ten times, because cause and effect are not empty. We just work hard and don't ask about the harvest.

Sometimes the effect is obvious, sometimes it is not. Just because it's not obvious doesn't mean it's not, but you didn't see it.

If you are eager to see the effect, there may be bad results. Keep reading, read every day, the more the better, and it will be effective in time.
