It depends on what you mean by “right away.” It’s different for everyone. Some might require more “time” to plan their next incarnation, depending on the complexity of the challenges and experiences they want to encounter. Time as we know it is different outside of this simulation; there is no set time for any given entity.

A belief system held in a previous lifetime might be strong enough to carry on after passing and take time to drop away, such as a belief in a soul sleep or a Hell-like existence that one goes to after death. This belief will take “time” to fade before their next incarnation.

Furthermore, an entity might want to wait for a specific “time” period to incarnate, where only the lessons they need to learn will exist. For example, if an entity wants to experience life where everyone is connected through social media, they might wait until the inception of the internet. Different periods provide different learning opportunities, which is why you see population booms and busts.

Some entities wait to incarnate with others who are currently in other lifetimes and with whom they want to share a lifetime, then incarnate together in a specific time period.

Others might have committed suicide in a previous lifetime and need a certain degree of healing before they are ready to reincarnate. This healing can help stop the momentum that could lead to another act of suicide in a future lifetime. They might need to analyze and more closely plan a future lifetime where the tests are less severe, thus preventing a repeat act.

It all depends—there are many variables.
