The five disadvantages are widowhood, widowhood, loneliness, loneliness and disability. They have explained all the specific explanations, so I won't go into details here. Who has five evils and three faults? Someone who snoops on secret wills. The world has its own rules, and those who spy on secrets and change the rules of things will be punished by God. The development of things has its own cause and effect. If we force ourselves to change the cause and effect, it will lead to accidents. Tell me about a specific fortune teller. Of course, a liar on the roadside is not a fortune teller. Combining the Book of Changes with reading hands is actually spying on secrets and will actually be punished by God, and this kind of fortune-telling is time-consuming and laborious. My roommate's college teacher teaches metaphysics. Because of the harmfulness of five evils and the time-consuming and laborious fortune-telling, she only counts three people a year. Moreover, at least half of the money earned by fortune telling should be done for charity, otherwise the money can't be kept by itself. Even the mayor of their city (a provincial capital in the northeast, confidential) and the director of the State Administration of Taxation asked her for fortune telling to reach the top. It is precisely because of the consequences of spying on secrets that many predictions are vague, otherwise the results will be very tragic soon. And some destiny takes a hand's things, predicted by Taoist practice, have escaped. In fact, causality is only disturbed, and it will hit with more violent causality. As the saying goes, they can't escape for a while. Comparatively speaking, Buddhism is much milder. Buddhism changes the operation of things from the root of cause and effect, solves problems from the root of cause, and the consequences naturally change. This is natural. So there is no such thing as five disadvantages and three deficiencies in Buddhism. In short, five disadvantages and three disadvantages are for those who spy on secrets. Whether you say it or not, as long as you spy on the secret, it is actually interfering with the operation of things. Inaction may also change things, but the result is much weaker. If you just take metaphysics as an interest and just have fun, that's nothing. If fortune-telling is used to change Feng Shui and change the operation of natural cause and effect, there will be retribution.
I won't recommend Taoist books to you. The Book of Changes is the main one. I usually regard the Book of Changes as a teaching material for self-cultivation and dealing with people. You can read the Book of Changes explained by Ceng Shiqiang as a model of your foothold in the world.
