The Mishna states that “The Holy One, Blessed Be He, will ultimately cause every tzaddik to inherit 310 worlds” (Uktzin 3:12).
Why is each and every tzaddik given 310 worlds?
Wouldn’t it make more sense for the tzaddikim to share these worlds?
What can a tzaddik do with so many worlds?
It must be that the ultimate reward for tzaddikim will be that each tzaddik will be able to create his own complete world, a world that truly suits him, his desires, and his dreams.
Presumably, once he accomplishes this, one world will not be enough.
A person needs 310 worlds in order to be everything that he wishes simultaneously, each world containing a different, unique version of him.
In our worldly existence, where many more than 310 of us must coexist, we often get in each other’s way, to the point where we must live in a reality where the internal and the external do not correspond.
This world, by its very nature and structure, is full of falsehood, and in a world of falsehood, the choice between truth and falsehood does not exist.
Hence, our recurring question in this world is not whether to be truthful or not; in actuality, the whole truth was never within our grasp in the first place.
