External forces may be strong enough to cool the sun or heat the moon but determined practitioners will not let them interfere with their endeavour. Once upon a time a king was riding in a chariot and noticed a praying mantis standing on its hind legs in the road trying to block his progress. There may be those who misunderstand the teachings but they are not capable of overthrowing Dharma. One cannot judge enlightened people by their actions. One cannot say whether thay are sinful or sinless.
Sages appear no different from ordinary people, yet indeed they are.
This may create problems. Since the time of Buddha people have found faults in the actions of saints and sages by relying on their own, narrow-minded world view. Sages and sound practitioners are open-minded and have no concern for conventions others may prize highly. An elephant treads a wide path. Prejudiced people are like rabbits that scamper along narrow paths and hide in burrows.
