- Know, every generation has one main tzadik through which all the energy is channeled.
- When this tzadik dies the generation is over.
- Generations vary in length.
- Another tzadik now gets the position. He is already alive he just didn't have the position.
- Since he is an a lower level everything goes down. Since it is all filtered through him.
- Every one goes down. Meaning it's a gradual change, the top of the lower level is similar to the bottom of the higher level.
- Some one born after the change is really affected. Some one born before at least had the start in a higher state.
- This is why the mishnah in Avos says Moshe to Yehoshua....
