Can a being simultaneously be in a higher and lower density at the same time?

[Nau7ik]

For example, I often read about “5th Density Wanderers doing a 3rd density incarnation”.

To my understanding, if someone is in 3rd density, they experience themselves as a physical material person separate from other physical material persons.

I used the wanderer as an example. This could be any being.

How can a 5th or 6th density being incarnate on Earth and live a life as a human? Wouldn’t they be back in 3rd density and need to graduate to 4th density again? This doesn’t make any sense to me.

You understand correctly. A 5D wanderer may choose to wander in 3D. He must take physical incarnation to do so, which means that his mind becomes veiled and he is an earth native for a certain period of time. He lives that reality. During his wanderering he is not occupying 5D. However he may likely have a social memory complex who occupies that position. Again, he is veiled from this awareness during the incarnation.
This 5D wanderer will have to meet the same requirements that earth natives do to graduate. Upon graduation he may decide to go back to his home density or continue wandering.

This constitutes a great sacrifice on the part of the wanderer because he is willingly sacrificing his higher spiritual awareness and abilities to incarnate in 3D to aid the planetary vibration. The danger is that he may get swept up in karma during his “forgetting.” STS negatives think this is too great a risk so they usually abstain from wandering, but it is not unheard of the negatives wander.
