My way of training people involves some suffering, because suffering is the Buddha’s path to enlightenment. He wanted us to see suffering and to see origination, cessation and the path. This is the way out for all the ariya, the awakened ones. If you don’t go this way there is no way out. The only way is knowing suffering, knowing the cause of suffering, knowing the cessation of suffering and knowing the path of practice leading to the cessation of suffering. This is the way that the ariya, beginning with stream entry, were able to escape. It’s necessary to know suffering.
