They don't joke with Kabbalah. Anyone who studies the secret sciences must definitely test their knowledge.
Checking with authentic sources is an important part of learning.
The material taught by Kabbalists is complex, but there are proven methods of assimilating it.
In the Middle Ages, the categorization of the Sephiroth was developed.
According to these categories, all Sephirs are included in the four Kabbalistic worlds.
One of these worlds is the World of Yetzirah.
