Alternate Realities

The world we live in seems to made up of many alternate realities - people's perceptions of reality vary greatly, to the extent that they perceive the world in completely different ways. What one might consider "unrealistic" can be the reality in which another person lives.

Each person, by how they choose to perceive their surroundings and circumstances (much of which are the result of their own choices), chooses and creates their version of reality.

According to Judaism, we are partners in the world's creation. After the creation of the world, it is written that G-d completed the heaven and earth and rested on Shabbat from all of the work he created to do:

"(1) Now the heavens and the earth were completed and all their host. (2) And G-d completed on the seventh day His work that He did, and He abstained on the seventh day from all His work that He did. (3) And G-d blessed the seventh day and He hallowed it, for thereon He abstained from all His work that God created to do." (Breishit 2:1-3) 

The creation of the heaven and earth was completed, but it then says that God rested from his work, not that he stopped or finished, which seems to indicate resuming it after the Shabbat, indicating ongoing creation on G'd's part. And we in our actions are partners in that ongoing creation, by having children, by refining and protecting the word around us and ourselves - and I would say also by our perception and beliefs which direct our actions, through which we create our realities, and through which various cultures create their realities. What world and what reality do we want to create - and what do we actually create?
