Children are the bridge between all Consciousness dimensions
Children during their very first years still live in a Soul level without been fully immersed into the human experience.
Even more importantly, they have a very high degree of Presence, a vibrational quality of the Source rather than the Soul.
Childhood is not an age definition of human beings as we limit it to. It is rather a hybrid state of consciousness bridging the other interdimensional gaps and is present in all dimensional states..
