Why does karma in Buddhism never work?

Normal, one thing, cause and effect are not happy at all, not without reporting, not yet.

In both cases, it is estimated that you are new to Buddhism and have little confidence. This is your unjust creditor blocking your way. You can ask the predecessors who studied Buddhism if they were all bad at first. Generally speaking, people who study Buddhism will have a bad memory in the first few years when they first come into contact with Buddhism and plan to practice. I just, I just studied Buddhism two years ago and can't recite it. This shows that your thinking is right. Your enemies are afraid that you are really on the right track and will not pay back your debts, so they will try their best to hinder you and make you lose confidence.

You can do more merits, repay them, tell them well, don't get in my way, and I will reward you for my achievements in the future. Then you can recite the Diamond Sutra, Buddha's name, Guanyin Bodhisattva and so on, and return all your merits to them. It won't be long before you get well.
