What do you think of the bye-bye cup?

There is no such thing as "holy grail", "yin cup" and "yang cup" in Buddhism. "Holy Grail, Yin Cup, Yang Cup" is a gimmick that charlatans attach to Buddhism to fool ordinary people.

The so-called "cup" is actually a very traditional divination thing like cashew kernel. It consists of two parts, one is flat and the other is protruding.

When divining, first ask the questions to be divined, and then throw them on the ground. If a plane is facing up and a convex surface is facing up, it is "grabbing the cup", which means good; If both pieces are flat, it is a "laughing cup", then it is a "positive cup"; Both pieces are convex upward, indicating "stable cup" and "negative cup", indicating bad. * * * Throw it three times.
