Some espouse this idea – ‘…他是真的欺骗我们，我们随他…’ (If they really bully or cheat us, we let them do it.) The idea is to let them express our negative karma, so as to wear it out, and to just accept the suffering they inflict on us graciously. This doesn’t seem healthy, because it allows evil-doers to go scot-free. They are also likely to harm more people. It would be partly our fault if we let them off without even any admonition. If we don’t help the evil to see the error of their ways, who will? Even the Buddha tells off evil-doers he comes across – to educate them.
It seems selfish to want to ‘pay back’ others our ‘karmic debts’, while letting them create negative karma. What we can do is to counsel the person to change his/her ways out of compassion; not blame. But if he/she doesn’t change, that’s would wholly be his/her problem. If we really get bullied and there is absolutely nothing we can do about it, we should then let it be. But is there really nothing we can do? If one lacks compassion to help those one is capable of helping now, there would be lack of Bodhicitta in the moment. There is no other way to practise the Bodhisattva path, than to work with our present limitations.
