Answer: Joyful music is not mindless partying. Rather, it has to awaken a good feeling within me, sympathy for what is happening. At the convention, as well as every day, we must imagine our future state that we aspire to, from which we want to receive an illumination, a glow, an influence. Let the Light that reforms come from there and draw us there.
Looking at something beautiful, I am automatically drawn to it. But in this case I have to imagine the beauty myself, as an exercise before and during the convention. In December we will immerse ourselves in the world of the future for 72 hours. We have a single vessel in which a general bestowing force becomes revealed and we all dwell in mutual bestowal.
What do we discover by that other than a feeling of euphoria? What are our relationships? How do we interact in the family, among friends, at work (with our coworkers, employees, and employers), in the economy of the new generation, in ecology, in society? We are entering a new world and are starting to check its details: culture, upbringing, science, our attitude to all kinds of things…
And that’s where music can help us develop the right approach to life. And it doesn’t matter if it has words or not.
However, music should not draw me to any sad thoughts, to anything reminding me of a descent or despair. And this prohibition is effective in our day-to-day work as well. Sad music, the left line can only be used if I have built a strong right line ahead of time and am in it. As Baal HaSulam writes, only half an hour a day can be spent on critical self-analysis, on the condition that I worked in the right line for 23.5 hours.
