Answer: We consider life as good according to what is good for us.
In our time, however, having uncorrected connections between ourselves, we cannot feel good. We see that the world is falling apart because the upper light descending upon it wants to fill it and the world feels its oppositeness to this light.
The closer spiritual goodness is to our world, the worse we feel. The nearing of the upper light gives us a sense of darkness because we are uncorrected, opposite to it. Therefore, if we want to feel the blessings and all the goodness, we must change ourselves to be similar to the upper light so we do not plunge into problems and crises because the light is coming closer and closer to us. In other words, we have to unite on the level of this world. That is the problem.
For example, the news announces that an asteroid is on its course to Earth and that the planet is in danger, people should feel themselves in danger, the upper light is coming closer to us, the Creator wishes to be revealed to the creations. This is why we are called “the last generation.”
We have entered a path of increasingly escalating pressure on us. This is why the science of Kabbalah has become revealed; it explains that we have to start adapting ourselves to the upper light to become somewhat similar to it.
We are a Kli (vessel of the soul), the Creator is the light. We can become similar to Him only if we unite between ourselves. In other words, if we wish for a better future, we must unite.
