There is a discernment of the next world, called “faith,” and there is the discernment of this world, called “attainment.” It is written about the next world, “Will be satisfied and will be delighted,” meaning there is no end to the satiation. This is so because all that is received through faith is unbounded.

Conversely, what is received through attainment is limited because anything that comes into the Kelim [vessels] of the lower one, the lower one limits it. This is why there is a boundary to this world.
