The separation comes from our own degree of separation within our own energetic vibrational frequency.
In lower frequencies, things "appear" to manifest slowly.
In higher frequencies, things "appear" to manifest or occur much faster.
There is no slower or faster in occurrence. It is how it "appears" depending on the frequency of existence in "that moment".
Physical reality is much denser, so it "takes longer" to appear in the physical. Not really, but that is how it appears.
Now, the lowest vibrational frequency in ones energy will dictate which is truly going to manifest. So if one "wishes" for something, but their underlying belief is unworthiness, lack or fear then that is what will manifest. Wishing all day won't make it happen if there is a more dominant frequency present. This is why TRULY clearing out anything of a low vibrational frequency is imperative for each on an "individual" level.
Learning frequencies, learning the purpose of clearing, releasing helps us to understand how this affects us. Frequencies do not allow us to any longer "hide" from those things we used to.
When one can truly understand how frequencies work within their own energy system, then they can choose to release those things that hold them back.
It is not the conscious thoughts that dictate, but the unconscious thoughts that one does not pay attention to. This is why being conscious in every moment of the unconscious state is imperative.
Frequency transformation is imperative for changing what one wishes to manifest in their own reality.
When one can be SO conscious, SO present that moments slow down to one, then they can actually "switch" from their reality manifesting "for" them to one of CREATING reality.
