Answer: No. Today this is no longer necessary.
In our day people have lost the desire to get married, raise a family, invest in a family, and the education of children is a big hassle for them.
Our generation was educated in a completely different way. Everyone had to get married, bring children into the world, educate them and give them a direction in life. These questions were always in front of us. But today, as a rule, parents aren’t very concerned about these things.
Comment: But in principle nature obligates us to live in a family.
Answer: That is how it once was, but for the new generation there is no need for this. In our day marriages are no longer necessary conditions even for those who want to develop spiritually.
My teacher Rav Baruch Shalom Ashlag obligated his students to marry and only someone who married was considered to be his student.
Unfortunately, I cannot demand this from my students because the wisdom of Kabbalah must extend and be disseminated all over the world. If I placed any conditions, we would not succeed in disseminating the wisdom of Kabbalah. The main thing is that people should hear and know at least a little about what the wisdom of Kabbalah is, and that is how the circle of those who are interested will gradually expand.
But someone who truly wants to be seriously involved with the wisdom of Kabbalah on one of the stages of spiritual development will need to think about solving the problem of the family. A person who learns about the nature of the spiritual world feels that he must himself be like nature, and so he is obligated to have a second half.
