Answer: The world is Malchut of Infinity, while all other worlds are separate, particular states in it that reveal its specific qualities in relation to us in order to help us become fully part of it.
“Traveling around the Creator’s world” means attaining Malchut of the World of Infinity and revealing the entire might and wealth of the connections among its parts, which connect and supplement one another.
I don’t have anything else to say because words cannot describe what happens Above once good and evil, truth and falsehood unite. They unite and complement each other, and we reveal this inside us, in the common desire of all the souls, called Malchut of the World of Infinity.
This is called “traveling around the Creator’s world.” It’s when we can use all the forces and all the desires of Malchut of Infinity, attaining each of its details and all of them together.
The most important pleasure is “when doubts are resolved,” meaning when things that seem opposite and hateful to one another suddenly unite. That is when love flares up among them, forming a place to be filled by the Light.
That is how a person “travels” around the Creator’s world, checking all of the harmony in which Malchut of the World of Infinity resides.
