The Zohar brings the verse ''towards evening" to discuss when the beginning of the rule of the erev rav [the mixed multitude] over the Jewish people would begin. And according to the way the Gra understands it it is referring to 1990 A.D. or about 15 years ago. [This Gra is on Tikunai Chadashim on the Hazohar page 34 by the standard numbering on the verse about Isaac going to mediate in the field which the Tikunim interprets as meaning to get rid of the mixed multitude.]
"Evening" in Hebrew is the same word as "the mixed (multitude)."
For he understands 1240 to be the sixth thousand year period. 1740 to be dawn. And the middle of the day is 1990. That is when the mixed multitude would gain control over the Jewish people. This explains at least to me the problem with cults that have infiltrated and taken control.
Cults have the ironic aspect of fish bait. It tastes good to the fish until it feels the hook. But by that time it is too late. Cults are like classic O' Henry story. The unexpected ending. Or maybe more like Edgar Allen Poe.
What ever you do, don't go near one for Passover, if you value your family, and wife and children. They are not openly hostile because they need donations. They are as friendly as fish bait.
There is no more Noah's Ark.
I have tried to make my own home or apartment wherever I have been into a kind of Noah's Ark. It just does not seem to work. The kelipot somehow get in.
I urge everyone to leave the cults--Jewish or otherwise. Go home. Find a job. Live like a mench, not a slave to some charismatic leader. Cults are organized in layers. Everyone can join but only the initiated know the real agenda. Everyone else are just pawns.
And if you are wondering if what you are in is a cult then take my word for it; it is. The facade will eventually evaporate leaving you with the emperor's clothes.
[For authentic Jewish experience learn Torah. That is have in your home an Old Testament and the basic set of the Oral Law, the two Talmuds (Bavli and Yerushalmi), Tosephta, Sifra, Sifri, Mechilta and Midrash Raba. Don't go near the cults--even to learn Torah. Better to go to the beach or make a barbecue than to a cult.] The Divestment from Israel movement is just a direct result of our problem of not divesting in cults in our midst.
Appendix
1) The comment of the Gra is not on the Tikunai HaZohar. That is after the printing and publication of the Zohar and Tikunai Hazohar there was a fellow that found some more writings from the same source material. He printed them and called them Zohar Hadash and Tikunim Hadashim. That was right before Spanish Jewry were kicked out. Nowadays all four books are fairly standard.
That is Zohar, Tikunai HaZohar, Tikunim Hadashim, Zohar Chadash.
I used to go straight to Isaac Luria and Moshe Kordovaro. [I also spent a lot of time on the Nahar Shalom by the Reshash, Shalom Sharabi and prayed with the Sidur of the Reshash. First the small one. Then after a few years someone told me that in Mea Shearim someone had printed the large sidur of the Reshash, so I got that --it was very inexpensive. I should mention that the large one is considered more accurate. Mordechai Sharabi said the smaller one has mistakes. In any case I highly recommend the large sidur of the Reshash both for learning and praying. I don't learn this at this point but it is an important part of education. If you do have time for the whole body of literature then I think that at least the Eitz Chaim of the Ari should be learned.
