It is even more difficult to forgive all beings. In fact, a true Buddhist must make a vow to forgive all sentient beings. See the twelve wishes of the pharmacist Buddha. The first wish was to benefit all beings, not himself, so it came true soon.
Many people who study Buddhism, meditate or practice monasticism often say to me, "Teacher! I haven't made any progress. " Alas! Do you want to make progress in behavior and thought? If there is progress, then there is really no Buddhism and justice! Everything is for yourself, selfish, so what should you do if you make progress? How is he?
So don't ask why there is no progress, no achievement, and why there are so many troubles in doing things. Ask yourself first, if you have a heart and a wish. Did a few good things?
