I have been reading this. It is a Buddhist book of fables. I have found that when it comes to understanding profound truths, all religions have the same problem. The general masses have difficulty understanding and appropriating wisdom.
The first fable is about this fool who went for a meal. He blamed the food for being tasteless so the host added some salt, and he found it tasty. He thought "the taste comes from the salt, if I add more, it will be even better". He shallowed a whole cup of salt, and upon realising his foolishness, spit them out. What is the moral of the story?
