Question: Why is nighttime the most productive time for mental activity? In principle, Kabbalists always studied at night when the concentration of thoughts is much clearer.
Answer: Firstly, it is physiologically conditioned because a person feels that during that time he has nothing else to do and he can concentrate on some work while everyone else is asleep.
Secondly, at that time, not many stimulating centers are activated in him, and therefore he can more easily concentrate on one thing.
Thirdly, if we are talking about spiritual work, then this is the time when you really need to connect to the spiritual root, root to branch or branch to root. At that time, new desires are created in which a person will continue to acquire an attainment.
Such work begins from midnight onward. Therefore Kabbalah encourages people to get up at twelve o’clock at night and start studying. Twelve at night, midnight, is not half of our night, but a conditional night. If you break the whole night from sunset to the appearance of the first ray of light into twelve parts, then the middle part, the sixth, conditional hour, will be midnight.
The night hour can be forty minutes, fifty minutes, or an hour and twenty minutes. We use mechanical clocks, but in general, in nature, clocks are not mechanical but rather solar and lunar. Therefore the hours are conditional.
Our body works the same way according to its internal conditional clock. The human body works completely differently during sleep in winter and summer. All this is taken into account in Kabbalah. That is, night and midnight are purely astronomical values and not mechanical according to the clock, which ticks no matter where and how.
Comment: But there are different regions.
My Response: Man is connected with nature; he is an integral part of it and cannot be separated from it.
And the regions are indeed different. Therefore there is a problem of how to study. But it is believed that it is still better for us to study together. This is most important.
Baal HaSulam writes that joint study, joint appeal, and joint actions override all other parameters.
