Q: Which is more important, to study the wisdom of Kabbalah, or to be nice to others?
A: Treating others nicely is not real if it is not based on spiritual attainment. We see how in our days the family disappears, and in five or six years, the concept of the family will cease to exist. Even today in many families in Europe, husbands and wives work in different cities and meet only on weekends.
The will to receive (egoism) will grow to such an extent that even a tiny unit such as a family will no longer be able to exist. That disintegration will continue until humanity comes to realize that it must live by equivalence of form with the Upper System, and that this is the only way for it to ever be happy.
Only then will it understand and be able to actually do something good for itself. Then, too, the family will return to being a family, but only through the wisdom of Kabbalah.
Man and woman in our world are a consequence of the spiritual structure called ZON DeAtzilut (Zeir Anpin and Nukva of the world of Atzilut). A family can exist correctly only if it functions similarly to that spiritual structure.
People will be so immersed in their own pains that they will resolve to build their relationships on spiritual foundations. Such a spiritual attainment will show man the perfection of it, in order for him to be able to do the same in our world. Until then, there will not be any affection among people.
